Abstract

A pushbutton switch operator assembly including concentrically arrayed tubular members permitting dual action of an actuator to release switch contacts from a first maintained position to a second maintained position either by a rotative manual operation of a tubular actuator or by manual axial "push-pull" actuator operation. This dual action is provided by longitudinal movement of a switching member having a cam profile acting against spring bias of a detent member, and wherein this longitudinal movement is obtained by said manual "push-pull" operation or by a camming action provided by mating ramp surfaces during rotation of the actuator with respect to a stationary supporting member.
