MDA-111

MDA-111 is a series MDA miniature adjustable pressure switch. It is used to sense differential pressure. The switch features field adjustable set point and gold inlay contacts. The lightweight and compact size make the MDA ideal for any application with space constraints. Applications include industrial, HVAC, pump and motor control, medical, automotive, pools and spas.
