ABSTRACT:
A safety switch has a mobile contact integral with a control lever which is removably held on a switch body in an operative contact-making position by a spring-biased disc. When the lever is tilted in any direction, or axially displaced, cam surfaces of the switch body disengage the lever from the disc to break the circuit, the disc preventing unintentional replacement of the control lever.
