ABSTRACT:
A power switching circuit selectively connects an electrical load having first and second input connections to any one of a plurality of branch power circuits. Each branch circuit includes a first and second conductor defining a relative voltage therebetween. The power switching circuit includes a selector switch for selecting which of the branch circuits is to be connected to the load. A triac is electrically connected to the first conductor of each branch circuit and to the first input connection of the load for selectively electrically connecting one of the first conductors to the first input connection. A triac is electrically connected to the second conductor of each branch circuit and to the second input connection of the load for selectively electrically connecting one of the second conductors to the second input connection. A control is operated by the selector switch for controlling the triacs to connect the respective first and second conductors of the selected branch circuit to the first and second input connections of the load.
