An electrical switch includes a rocker-type actuator adapted to be pivoted between first and second positions within a housing in order to close and open switch contacts. The actuator slidably supports a latch which normally engages the housing to prevent the actuator from being pivoted to its switch-closed position. By pulling on the latch and then lifting on the actuator, the actuator may be pivoted to its switch-closed position; the two-step operation protecting against accidental actuation of the switch. The switch housing is mounted with a snap fit in an opening iun a panel. A lug on the housing engages the underside of the panel to prevent the switch from being pulled out of the opening in the event a heavy lifting force is applied to the actuator without first releasing the latch. One switch contact is adapted to pivot and slide on a fulcrum which is laterally offset from the pivot axis of the actuator in order to delay opening of the switch relative to the position of the actuator.

A safety switch adapted to be located in a generally rectangular opening formed through a mounting panel having inner and outer sides, said switch comprising a hollow body of generally rectangular cross-section and sized to fit in said opening, said body having a pair of laterally spaced side walls and having first and second end walls extending between and generally perpendicular to said side walls, said walls having outer ends, a peripheral flange on the other ends of said walls and engageable with the outer side of said panel to prevent said body from moving inwardly through said opening, resilient finger means on said body and engageable with the inner sides of said panel to releasably hold said body against moving outwardly through said opening, a switch contact in said body, a switch actuator, means mounting said switch actuator within said body for pivoting about a predetermined axis between first and second positions relative to said body to change the state of said switch contact, said axis extending generally perpendicular to said side walls, said actuator having a handle portion located adjacent said first end wall and adapted to be forced outwardly to pivot said actuator from said first position to said second position, means for selectively latching said actuator against movement from said first position to said second position, and retaining means on said first end wall and engageable with the inner side of said panel independently of said fingers to prevent said body from being pulled out of said opening if said handle is forced outwardly when said actuator is latched against movement from said first position to said second position.
