Energy Harvester

No power supply, battery or maintenance required. Power generated with a low-force push.
Energy Harvester

The SPGA Series Energy Harvester is a compact power-generating device employing electromagnetic induction to generate power with each push or release. Combined with low-power wireless technology, the device can function as a switch. It can be installed away from a main board, for example, in places where connection to a power source, or battery replacement, is difficult, and is ideal particularly for frequently operated equipment.
