An electrical switch wherein electrical contacts are carried within a hollow body and an operating member is slidable in the body to operate the contacts. The operating member is in the form of first and second similarly shaped and interengaged parts the interengagement of the parts, permitting limited movement of the parts relative to one another in the direction of movement of the operating member relative to the body. A spring is trapped between the interengaged parts and urges the parts away from one another in the direction of movement of the operating member whereby during initial movement of the operating member from a rest position the contacts are operated and no relative movement between the first and second parts of the operating member takes place, but during further movement of the operating member relative to the body in the same direction, the first operating member part is moved relative to the second operating member part against the action of the resilient means.
