Abstract
A bi-stable interlock arrangement allows two circuit interruption devices such as electric circuit breakers and electric disconnect switches to be interlocked such that only one such device can be turned ON at one time. The interlock is used with main and auxiliary power sources to ensure that only one source of electrical power is activated at one time.
