Energy Harvester SPGA Series

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

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.
