Notes are common to this series/models

  1. This site catalog shows only outline specifications. When using the products, please obtain formal specifications for supply.
  2. Please use 1.6mm thick PC boards.
  3. Please place purchase orders per minimum order unit (integer).
  4. This products can be used in vehicles.
    Although these products are designed to perform over a wide operating temperature range, please ensure that you receive and read the formal delivery specifications before use.

Cautions

  1. When terminals are exposed to mechanical stress during soldering, it may cause degradation in deformation and electrical property.
  2. Through-hole PC board, or a PC board thickness other than the recommendation may cause larger heat stress. Prior verification is highly recommended.
  3. In prior to the 2nd soldering swith shall be stable with normal temperature. It may cause deformation of swith, loose terminals, terminal removed from PC board, and / or degradation of electric property.
  4. Verify samples with actual mass production conditions.
  5. After soldering, do not wash switches with a solvent, etc.
  6. The products are designed and manufactured for direct current resistance. Individual consultation is recommended for use of other resistances such as inductive (L) or capacitive (C).
  7. The sizes of holes and patterns on a PC board for mounting a switch, be asper the recommended dimensions in the product drawings.
  8. This switch is designed for manually operated units. Must not use this switch for a mechanical detection unit. For detection purposes, please use our detection switch.
  9. The switch will be broken if impact force or a greater stress than that specified is applied. Take great care not to let the switch be subject to greater stress than specified.
  10. Do not apply a force from the side of the stem.
  11. Be sure to push the center of switch for “without-stem” type. Extreme care is required for a hinge structure type, as the activation point may shift when it is pressed down.
  12. The circuit setting (software setting) shall be ensured for error-free operations, caused by bounce and chattering as specified by each model of the switches.
  13. Prior verification is needed to ensure that no corrosive gas-generating components are used near our switch. It may give negative influence such as contact failure.
  14. Contact resistance of a carbon contact type may vary depending on push force. Confirm that it functions sufficiently in using TACT Switch™ with a voltage divider circuit.
  15. Be aware of dust intrusion into a non dust-proof TACT switch™.
  16. Storage
    1. Store the products as delivered, at a normal temperature and humidity, without direct sunshine and corrosive gas ambient. Use them at an earliest possible timing, not later than six months upon receipt.
    2. After breaking the seal, keep the products in a plastic bag to prevent out ambient air, store them in the same environment as above, and use all as soon as possible.
    3. Do not stack too many switches.
    4. Store the key switches in released position.
  17. TACT Switch is a trademark or registered trademark of Alps Alpine Co., Ltd.

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.
