ABSTRACT:
A three position switch which selectively interconnects isolated conductors on a printed circuit board is disclosed. In one embodiment, pressure sensitive conductive elastomer pads, disposed in the switch, are brought into contact with isolated conductors on a substrate. A sliding switch actuator, having a cam surface with indentations, is then used to selectively apply pressure to the conductive elastomer pads and thereby selectively connect the isolated printed circuit board conductors. In another embodiment, a three position switch is shown including a plurality of conductive pads, flexibly attached to a switch casing, which are positioned above printed circuit board isolated conductors and then selectively flexed downward into contact with the printed circuit board conductors by moving a sliding actuator arm having a cam surface. The conductive pads are normally separated from the printed circuit board conductors by a flexible rubber shoulder which forms a seal around the contact area and is flexed outward while maintaining the seal when the conductive pads are flexed into contact with the printed circuit board conductors.
