Momentary contact switches are discrete electromechanical devices that complete or interrupt a circuit only whilst actuated, returning to their default state upon release, and encompass push-button, tactile, and plunger-actuated configurations manufactured to MIL-DTL-3950 and related defence standards, using gold-flashed or silver-alloy contacts rated for the low-current signal and high-cycle-endurance demands of aerospace control panels and cockpit interfaces.
