ABSTRACT:
An auxiliary add-on attachment is disclosed for use in combination with an existing rocker switch. The attachment includes a spring loaded latch mechanism which upon release drives the rocker button to an OFF position. The latch mechanism is released upon retraction of a solenoid plunger when the solenoid is energized by a trip signal which may, for example, be delivered from a timing circuit when a designated machine should be automatically turned off after a certain length of time, such as cathode ray tubes, computers, photocopy machines, etc. Depressing the rocker button back to its ON position loads and resets the latch mechanism.
