ABSTRACT:
A reversing switch for use in a multi-phase electrical system, and in particular a three phase electrical system has a conductor for linking the input and output of one of the three phases. The reversing switch has two phase switches for reversing polarity. Each phase switch has a pair of stationary contacts and a moveable contact for reversing phase by switching between the stationary contacts. The moveable contacts of each phase switch are moveable in unison by a motor and associated transmission during switching of the reversing switch between first and second modes of operation of opposite polarity.
