Abstract
Micro-electromagnetically actuated latched miniature relay switches formed from laminate layers comprising a spring and magnet, electromagnetic coils, magnetic latching material, and transmission line with contacts. Preferably the miniature relay switches transmit up to about 50 W of DC or AC line power, and carry up to about 10 A of load current, with an overall volume of less than about 100 mm. In addition to switching large power, the device preferably requires less than 3 V to actuate, and has a latching feature that retains the switch state after actuation without the need for external applied voltage or current.
