Deltrol Controls 20239-84 SPDT momentary pushbutton switch is a single-pole, double-throw device that actuates briefly when pressed and returns to its default state when released. The 20239-84 designation identifies this specific SPDT switch for control circuits requiring a temporary contact change. In SPDT configurations, the common contact can be routed to either of two outputs, enabling simple signal routing or control signaling in electrical systems. With momentary action, it provides a temporary contact closure suitable for momentary input signals in electrical control circuits.
