The apparatus includes a protecting member protecting the switch and a restricting member restricting an object entering an opening of the protecting member. The restricting member has an opening smaller than the opening of the protecting member. The restricting member is movable in the direction intersecting the direction in which the actuating member passes through the opening of the restricting member. The opening of the restricting member is reduced in size to prevent an accidental operation while being insusceptible to a space in the apparatus or deformation of the apparatus.

Abstract: To prevent damage of a cord set used to charge a plug-in electric vehicle when the vehicle is driven away while the cord set is attached, an interlock can be provided to disable the vehicle. Such interlock may be based on a protective door over the charging receptacle being open or detection that a cord set is plugged in. However, in the event that the vehicle is in an activated state, the interlock is prevented from disabling the vehicle according to an embodiment of the disclosure. That is, undesirable disabling of the vehicle is prevented when either there is no indication of a cord set being coupled to the vehicle or the vehicle is in an activated state.

Abstract: An interlock assembly for a safety switch includes a linkage. A first end of the linkage is coupled to the operating handle of the safety switch in order that moving the operating handle results in a corresponding movement of the second end of the linkage into and out of an aperture in a bracket member. The bracket member is movably coupled to the safety switch enclosure by a fastening mechanism. When the cover of the safety switch is disposed in its open position, the bracket member is disposed in a first position preventing the second end of the linkage from entering the aperture and resisting undesired movement of the operating handle. When the cover is closed position, the bracket member is moved to a second position corresponding to the second end of the linkage being receivable by the aperture in order that the operating handle is movable.

Abstract: A self-adjusting interlock actuator assembly for a hinged cover is composed of a cover hinge attaching the cover to the apparatus and a pivoting switch actuator. A spring means connects the cover hinge to the pivoting switch actuator. The spring means is arranged such that the pivoting switch actuator is driven by the cover hinge via the spring means to actuate the interlock switch when the cover is closed. In this way, rotating the cover hinge about the hinge axis causes the pivoting switch actuator to rotate about its pivot axis, thereby causing the pivoting switch actuator to actuate the interlock switch.

The mechanical assembly includes an electromagnet drive plate to which the electromagnet of the solenoid is secured and an armature drive plate carrying the solenoid armature. A latch mechanism alternately holds one drive plate and then the other stationary so that the electromagnet and armature alternately move to effect reciprocal movement of the handle of the one electric power switch, and through the rigid strap, the handle of the second electric power switch.
