ABSTRACT:
Electrical switching apparatus comprises first and second plugs, each with a lead attached thereto, and a load socket which is connected to the second plug through a switching assembly. The first plug is connected to a wall socket controlled by a remote switch. The second plug is connected to a permanently live wall socket. The switching assembly comprises two switches, one operated by adjacent manual control means, the other being an electromagnetic relay operated, via the first plug and lead, by the remote switch. Each of the switches in the switching assembly has first and second positions. When each switch is in its first position, and when each switch is in its second position, the load socket is connected to the live wall socket. When one switch is in its first position and the other in its second position, the load socket is disconnected. In this way the load socket can be connected or disconnected by operating either the remote switch or the adjacent manual control means.
