ABSTRACT:
A magnetically actuated safety receptacle and plug characterized by a receptacle having a first pair of electrical contacts extending through a support member, and an over-center drop-out member hinged to the support member and carrying a second pair of electrical contacts. When a magnetic plug is inserted into a recess provided in the front of the support member the drop-out member is magnetically attracted towards the support member so that the first pair of electrical contacts and the second pair of electrical contacts abut to provide power to the plug. The hinge attaching the drop-out member to the support member is articulated so that the contacts can wipe against each other to remove any oxide build up. An industrial version of this invention includes a gas tight enclosure surrounding the drop-out member and the interior contacts to prevent accidental ignition of combustible gases.
