SYSTRON DONNER CORP. used those 'Mil-Spec' type push buttons, with '325' type incandescent indicator lamps. The Safety Systems division (Concord, CA.) sells industrial fire and overheat detection. So the typical system control / display box would have detectors wired in, and a 'press to test' feature would run a low voltage down the wiring, to detector, and back: That way virtually every portion is checked out. Used in aircraft, and some (military) heavy vehicles as well. |

These guys make some nice-looking switches of the type used in power-plant control rooms: https://www.electroswitch.com/products/utility-power-switches-relays/manual-standard-instrument-and-control-switches . And no power plant would be complete without a bunch of these! https://www.ametekpower.com/products/alarm-management |
