Abstract
Abstract An apparatus and method is disclosed for providing a rotor switch. The rotor switch consists of a rotor device positioned between a pair of printed circuit boards. One printed circuit board having conductive pads, coupled to the output of the switch, and the other board having a conductive strip, coupled to the input of the switch. A conductive spring, or similar conductor, is disposed through the rotor to couple one of the conductive pads to the conductive strip. A housing having a retainer that fits into exterior notches located in the printed circuit boards and the rotor acts to secure the rotor in place when rotational forces are exerted on the switch.
