Abstract
Switching apparatus for switching an electrical load between alternative sources of electrical power includes a pair of switches having their load terminals connected in common to the load and their line terminals respectively connected to the two sources. The mechanisms of the switches are interconnected by a reciprocating slide which is manipulated such as to connect one or the other, but never both of the sources to the load.
