Latching Airswitch 1/2" Threaded Spout SPDT

Latching relay with 21A load rating. SPDT - smaller 1/2" threaded spout (most air switches have a 9/16" threaded spout)- Air pressure alternates between open and closed circuit.
Eliminates the need for additional control components provided air pressure is adequate.
