ABSTRACT:
An electrical switching mechanism has a pair of arcuate spring contact members which are mounted in a casing. An aperture is formed in the casing for receiving an actuator member which may comprise a screw or other similar actuator member. A camming member is slidably mounted in the casing with one portion thereof abutting against one of the spring contact members. The camming member is urged by the spring contact member such that it is resiliently urged towards the aperture. The spring contact members are retained in the casing by means of casing guide elements in a position such that when a screw or other member is inserted in the aperture, the camming member is urged outwardly by the screw so that it retains its associated spring contact member in a non contact position with the other spring contact member. When the screw is removed from the aperture, the first mentioned spring contact member drives the camming member into the aperture with the two spring contacts being permitted to come into contact with each other. The switching mechanism can be used in an alarm system to provide a warning when the screw is removed in an attempt to steal a piece of equipment held thereby.
