CHERRY Energy Harvesting Wireless Switches are a compact and highly efficient system consisting of a generator and receiver. Energy Harvesting makes use of energy which is already available. Cherry's Energy Harvesting switch module works on an inductive basis along with an inductive generator. The inductive generator converts mechanical energy into an electrical energy pulse by continuously changing the direction of the magnetic field. The energy is converted in the energy management system into a constant supply voltage stretched out over time. This powers the radio electronics with transmitting antenna to send a radio signal.
