Abstract
A device adapted to be mounted on an existing multiswitch panel includes a plurality of spring biased trip rods which are adapted to engage the switch levers to move them to the OFF position when released. The rods are moved conjointly with the switches when the switches are turned to the ON position. Flexible detents block the return of the rods in the OFF direction until displaced by a single actuator rod operated by a programmed timer.
