ABSTRACT:
A unitized manual actuator assembly is attached to a printed circuit board for operating poppet switches mounted thereon. The actuator assembly comprises a two-piece housing having a pair of integral tube guides disposed in the housing. A pin is slideably disposed in each tube guide with one end protruding out of the housing for operating the switches. The internal end of each pin has an integral hollow cap covering and protecting the upper open end of its associated tube guide. A coil spring surrounds each tube guide and engages the integral hollow cap of the pin to bias it against a rocker member pivotally mounted in the housing. The rocker member has an operator portion extending through an opening in the housing and a pair of oppositely extending arms engaged by the hollow caps so that the pins translate in opposite directions when the rocker member is pivoted.
