Safety Standards

Safety Standards Outline

Safety standards are established by a country or an organization representing it to protect general users from electrical shock and fire hazards.
It establishes standards for electrical devices and components. For electrical equipment manufacturers, utilizing switches that have been safety-approved ensures the safety of the switch. The use of a safety-approved switch also simplifies at least one part of the process of obtaining certification by safety testing.

Major Safety Standards
Electrical Appliance and Material Safety Law
The conventional [Electrical Appliance and Material Control Law] has changed to [Electrical Appliance and Material Safety Law] and has been enforced since April 1, 2001. Electrical appliances are categorized into special electric appliances and parts (formerly Class A) and Electrical appliances other than the special electric appliances (formerly Class B) .
Special electric appliances are required to receive goodness of fit test at a certified test agency and to store the certificate. Also, penal provisions have been reinforced.
UL (Underwriters Laboratories Inc.)
Underwriters Laboratories Inc. (UL) is the American safety approving organization. Its purpose is to ensure consumer safety and protect them from fire hazards. State law requires that equipment to be exported to the United States utilize UL approved power switches or power switches meeting UL standards and capable of passing UL tests.
CSA (Canadian Standards Association)
Canadian Standards Association (CSA) is the Canadian safety testing association and tests electrical and other equipment to ensure the safety of individuals and prevent fire hazards. Provincial law requires that the power switches used in equipment for export to Canada be CSA approved or meet CSA standards.
SEMKO (Svenska Electriska Materielkontrollanstalten)
Svenska Electriska Materielkontrollanstalten (SEMKO) is the Swedish safety testing organization. Its purpose is to prevent electrical shock and fires due to home electrical appliances. Nearly all electrical appliances sold in Sweden must be approved by SEMKO.
BS (British Standard)
British Standard (BS) is the industrial and safety standards of Great Britain. It is made up of such organizations as the BSI and BEAB. It conducts investigations of electrical equipment for verification of safety. Electrical devices do not have to conform to this standard but those that do have a competitive advantage in the marketplace.
VDE (Verband Deutscher Electrotechniker)
Verband Deutscher Electrotechniker (VDE) is the German safety testing organization. It is particularly concerned with preventing hazards to human life and fires. Approval is not mandatory but fines are levied against those companies whose unapproved products cause accidents. Therefore, in reality, conformity is a necessity.
ENEC (European Norms Electrical Certific, since 1)
The “ENEC” mark is a common European product certification mark certifying the compliance of a product with the EN standards. Organizations that signed the ENEC agreement certify products. The mark has an identification number of these organizations that have tested and certified. The mark is applicable to power switches in our products.
Standard Certification System
CB Scheme
The ENEC mark is widely recognized across Europe as a common mark certifying compliance with European standards (EN). Accreditation is carried out by certification bodies party to the ENEC Agreement. It allows approval by participating countries (e.g. European states and China) to be obtained through minimal evaluation of parameters differing from IEC and national standards.
Mutual authentification system of the North American nations
A mutual authentification system is effective with the UL (in the U.S.A.) and CSA (in Canada) and the “C-UL-US” makes UL approved goods sellable in Canada, while the “NRTL/C” makes CSA approved goods sellable in the U.S.A.
Meaning of the Marking of Power Switch Ratings

Power switches for electronic appliances
Mainly power switches for electronic appliances such as TV sets, radios and amplifiers. However, if the voltage and current levels are below the ratings, they may be used in other electric appliances.
Power switches for general appliances
These switches are for use in appliances other than electronic appliances or motor appliances that have current surges. However, if the rating of the switch is 1/√2 or above the surge current of the circuit and meets construction requirements, it may be used in other devices.
Power switches for motor appliances
Mainly for appliances that are motor driven, such as copiers, vacuum cleaners, etc.
Explanation of Safety Standard Terms
Three insulation classes of the safety standards of IEC standards

Switches are classed according to their type of insulation.

Switches for Class I Appliances
Switches for use with appliances utilizing power plugs with ground pins having a normal level of insulation.
Switches for Class II Appliances
Switches for use with appliances having no ground pin and utilizing double or reinforced insulation.
Micro-gap Construction

This is one category of power switches under IEC standards and refers to switches with a clearance between contacts of less than 3mm (with 2.5kV impulse voltage). Switches with micro-gap construction bear the“ μ” mark. IEC standards place restrictions on uses of switches with micro-gap construction (for example, they cannot be used with outdoor electric tools or with computer equipment without power plugs).

Switches not covered in the Electrical Appliance and Material Safety Law

Switches with [structure specialized for building into machines] are precluded from the special electric appliances and parts, and are not required to undergo a goodness of fit test. However, the technology standard must satisfy no less than the special electric appliances and parts. The major reasons for preclusion from the Electrical Appliance and Material Safety Law are as follows : All of our power switches are precluded.

  1. All except for unipolar/single-throw, unipolar/double-throw, bipolar/single-throw.
  2. All with signal changing-over switch attached.
  3. All with lead, faston, wire-wrapping and printed terminals.
  4. All without knobs and handles for manual operation.
Approval type number

The approval type number means the type number on the safety standard described in the safety standard approval certificate or approval list. Therefore, the approval type number is different from the product number. There are cases where the approval type number varies with the acquired standard, rating, etc. even in the same series of products. When the set manufacturer applies for the set safety standard, the application must be made with the approval type number for the switch to be used.

Cautions

  1. The primary power supply changeover is regulated by safety standards, and its contents vary for particular destinations. Consult with us for special applications.
  2. An unstable contact may occur if the switch current is lower than 0.5A. For this case, consult with us.
  3. These power switches were produced for alternating current. For direct current, consult with us.
  4. Note that if the load is applied to the terminals during soldering, they might suffer deformation and defects in electrical performance.
  5. Use of water-soluble soldering flux shall be avoided because it may cause corrosion of the switch.
  6. When soldering twice, wait until the first soldered portion cools to normal temperature. Continuous heating will deform the external portions, loosen or dislodge terminals, or may deteriorate their electrical characteristics.
  7. Before soldering switches with locking mechanism, release the locks. If they are soldered without releasing the locks, the soldering heat may deform the locking mechanism.
  8. Be sure to release the locks before removing the knobs. Otherwise, the locking mechanism may be broken.
  9. Be sure to use the switch with forced travel positioned as close to the total travel as possible.
  10. Tighten the mounting screws by applying the specified torque. Tightening with a larger torque than the specified will result in malfunction or breakage of screws.
  11. When corrosive gas is generated by peripheral material of a set using the switch, malfunctions such as imperfect contacts can occur. Be mindful of this point thoroughly in advance.
  12. Storage method
    Store the products as delivered at normal temperature and humidity, out of direct sunlight and away from corrosive gases. Use them as soon as possible and no later than six months after delivery.
    Once the seal is broken, use them as soon as possible.

Measurement and Test Methods

Rotational Torque (Operating Force)
Measures the torque (operating force) necessary to rotate (move) the shaft (lever). Unless otherwise specified, measurement shall be made at ambient temperatures of 5 to 35°C, the shaft rotational speed shall be 60° per second, and the lever traveling speed shall be 20mm per second.
Shaft Wobble
Measures the amount of deflection at the specified position from the reference plane, with the specifiedbending moment, applied perpendicularly to the shaft from directions 180 degrees with respect to each other.
Withstand Voltage
Applies AC voltage to the specified spot for a minute and then checks for arc, burning, dielectric breakdown and other abnormalities. Respective terminals may be tested as a group. The sections described below shall be tested unless otherwise specified. However, if the section concerned is so constructed as to conduct, that particular part shall not be tested.
Insulation Resistance
Applies specified voltage to the specified locations and then measures the insulation resistance with a megger. The locations described below shall be tested unless otherwise specified. However, if the section concerned is so constructed as to conduct, that particular part shall not be tested.
Sections to be Tested for Withstand Voltage and Insulation Resistance
  • Between terminal and shaft (lever).
  • Between terminal and metal cover (frame).
Shaft (Lever) Strength against Push/Pull Actions
Applies a specified force in the axial direction of the shaft (lever) for 19 seconds and then checks the operating part and other sections for deformation, breakage, operating conditions, etc.
