摘要： A contact assembly comprising a plurality of pairs of spaced apart fixed contacts supported in an electrically insulating body, an actuator displaceable relative to the body between first and second positions, and a plurality of moveable contacts mounted on the actuator. Each moveable contact is positioned on the actuator so as to interconnect the contacts of one of the pairs of fixed contacts only when the actuator is in one of the first and second positions. Each fixed contact has two limbs defining an L-shape, one limb defining a single leg which extends through an aperture formed in a partition defined by the body and the other limb extending to one side of the leg to define a head supporting a terminal for gripping a wire. Each moveable contact is displaceable into contact with the leg of each of the respective pairs of fixed contacts on the side of the leg from which the head extends and on the side of the partition remote from the head.

摘要： According to the present invention, there is provided a safety switch operating mechanism comprising an engagement mechanism mechanically linked to a plunger, the engagement mechanism being arranged to receive an actuator such that insertion of the actuator into the engagement mechanism moves the plunger to a first position, and removal of the actuator from the engagement mechanism moves the plunger to a second position, wherein the safety switch operating mechanism further comprises a resilient member which engages with the plunger, and which resiliently resists movement of the plunger from the first position to the second position and thereby resiliently resists removal of the actuator from the engagement mechanism.
