Self-powered wireless switch

摘要

A wireless switch is provided having a twenty-year life energy harvesting arrangement for self-powering a wireless transmitter. The energy harvesting arrangement is implemented in one embodiment using a piezoelectric switch element. A tritium light source and photovoltaic device are used in a second embodiment, while a black light source and photovoltaic device are used in a third embodiment. The energy harvesting wireless switch arrangement of the present invention can be combined, for example, with a vehicle side mirror switch, to reduce the complexity of the wire harness feeding the door. The wireless switch can be located without regard to accessability of a wiring harness or connector.
