ABSTRACT:
A pushbutton switch capable of conversion from alternate action operation to momentary operation includes a housing, an elongated slider with a heart-shaped cam groove, a removable alternate action stop member, and a helical compression spring. The removable alternate action stop member is in the form of a rigid wire with an upturned pivot leg, a downturned detent leg parallel to the pivot leg and a crosspiece . The upturned pivot leg extends upward through a pivot hole in an upper tongue of the housing and the detent leg extends downward into the heart-shaped cam groove in the slider. A top opening in the housing communicates with the pivot hole and provides an area for side-to-side swinging movement of the crosspiece as the slider moves along a longitudinal axis and the lower end of the detent leg follows the heart-shaped cam groove. A raised cover connected to the upper tongue covers a portion of the top opening and protects the stop member from damage during assembly or use. The helical compression spring surrounds the slider and supplies an outward bias force to the slider. In addition, the helical compression spring has an end which surrounds at least a portion of the upper tongue and applies a longitudinal bias force to the upper end of the stop member which tends to bias the lower end of the detent leg into engagement with the heart-shaped groove.
