Abstract
A control circuit for a circuit interrupting switch having a non-stored energy operator reduces the time period between a switch command and a change of the switch contacts. The time period is reduced by prearming the mechanical operating linkage after each switch operation. By prearming the mechanical operating linkage, the linkage has less distance to travel and hence the time period between a switch command and a change in the switch contacts is greatly reduced.
