Abstract
A power transfer switch suitable as a bypass switch connecting a utility feed to a load comprises a bi-stable actuator selectively driven by a compression means charged by a handle. A latch retains the actuator until suitable power source conditions are detected to allow the transfer to proceed. The controller releases the latch and the actuator abuts breakers in sequence to effect a reliable make-before-break or break-before-make transfer.
