Patent ID: 7855344

Claim:
A reversing switch connected between three input phases and three output phases of an electrical system and having first and second modes of operation of reverse polarity, the reversing switch comprising: a first conductor linking a first one of the three input phases to a first one of the three output phases; a first phase switch comprising a first stationary contact adapted for connection with a second one of the three output phases and a second stationary contact adapted for connection with a third one of the three output phases, and the first phase switch comprising a first movable contact adapted for connection with a second one of the three input phases and being movable between a first position contacting the first contact when the reversing switch is operating in the first mode of operation and a second position contacting the second stationary contact when the reversing switch is operating in the second mode of operation; a second phase switch comprising a third stationary contact adapted for connection with the third one of the three output phases and a fourth stationary contact adapted for connection with the second one of the three output phases, and the second phase switch comprising a second movable contact adapted for connection with a third one of the three input phases and being movable between a third position contacting the third contact when the reversing switch is operating in the first mode of operation and a fourth position contacting the fourth stationary contact when the reversing switch is operating in a second mode of operation; and, a motor and associated transmission adapted for connection with the first and second moveable contacts to move the first and second moveable contacts in unison during switching of the reversing switch between the first and second modes of operation.
