United Electric Controls 10-C11 Pressure Switch

The United Electric Controls 10-C11 Pressure Switch is a compact, cylindrical unit from the 10 Series that provides a single SPDT output over a 10 to 150 psi (0.7 to 10.3 bar) setpoint range. It uses external adjustment via a screw, and wetted parts are brass with Buna-N diaphragm and O-ring, ensuring a reliable seal in harsh environments. The pressure sensing port is 1/8" MNPT brass, and the electrical connection is via a 1/2" MNPT conduit with 20" leads (3-wire), making it easy to wire into control circuits. Rated for up to 5 A at 125/250 VAC or 5 A at 30 VDC, the switch is built in a NEMA 4 enclosure to withstand moisture, dust, and outdoor conditions. This device features a single SPDT output and standard external adjustment for setpoint changes, and its compact form factor makes it suitable for HVAC, fluid handling, and general industrial equipment where space is limited and reliable pressure monitoring is required.
