Abstract
Abstract A push button switch module (10) is provided for mounting on a switch wiring chassis (56). A front housing (12) includes at least one push button aperture (24). An actuator pad (14) is mounted to the rear of the front housing (12) and includes a push button switch actuator (32) exposed in the aperture. A printed circuit board (16) is mounted to the rear of the actuator pad (14) at the rear of the front housing (12) and includes a switch pad (38) operatively associated with the switch actuator. A switch cap (18) is interchangeably mounted to the front of the front housing (12) at the aperture (24) and is movable relative to the housing for engaging the push button switch actuator (32).

(12) and including a switch pad (38) operatively associated
with the switch actuator; a switch cap (18) interchangeably mounted to the
front of the front housing (12) at said aperture (24) and
movable relative to the housing for engaging the switch
actuator portion (32) of the actuator pad (14); first snap-latch means (26) on the underside of
the front housing (12) for mounting the printed circuit
board (16) thereto, sandwiching the actuator pad (14)
between the front housing and the printed circuit board;
and second snap-latch means (48) for removably and
interchangeably mounting the switch cap (18) to the front
housing (12) through said aperture (24) therein.
