Glen;
Thanks for your suggestion. It isn't visible in the photo but there is a huge 12V relay (marked "US Army Air Corps") that is operated by this switch in series with an impact switch. If either the switch guard is snapped down or the impact switch is triggered, ALL of the 12V power is shut off. The indicator showing green "OPR" changes to amber "STBY" when this happens and the "POWER" indicator shuts off. As long as the battery switch is on, the "BATTERY" light is on.
Most of what appear to be toggle switches are actually Airpax switch breakers-- circuit breakers that are designed to be a toggle switch with a built- in circuit breaker. This way I can control electrical stuff individually as well as having circuit protection.
