Title: Electric switches

Abstract: The present invention provides an electric switch having a mechanism comprising an actuator, a contact member capable of being moved along a path by the actuator and two spaced apart electric contacts arranged along said path; wherein one of said contacts functions, in use, as a fulcrum and wherein said member is so shaped and the switch is constructed and arranged such that said member is moveable, from a first position in which it is in contact with said contacts, slideably with respect to said contacts and in so doing initially rotates in one direction and thereafter pivots about the fulcrum in a rotation of opposite direction whereby to come out of contact with the other of said contacts. The above can be applied to a host of switches including those with arcuately, linearly and rotary moveable actuators.
