ABSTRACT:
An automatic electric load transfer switch incorporates an over-the-center spring mechanism to operate switch contacts. The spring mechanism has a first position at which the electric load is connected to one electricity source and a second position at which the load is connected to another electricity source. The spring mechanism is driven by a solenoid activated cam shaft. An apparatus is provided for halting the movement of the spring mechanism at a position intermediate the first and second positions at which the load is not connected to either electricity source. The halting apparatus is releasable so that the spring mechanism can continue its movement between the first and second positions.
