Multiplex 751140 Pressure Switch Spst CI-80 CO-55

Product Description

The MULTIPLEX 751140 is a single-pole single-throw (SPST) pressure switch rated to close at 80 psi (CI-80) and open at 55 psi (CO-55). Pressure switches of this type monitor system pressure and signal a control circuit to respond when a set threshold is crossed. The 751140 is a commercial appliance component designed for use in Multiplex refrigeration and beverage dispensing equipment. Licensed technicians and commercial refrigeration service professionals install this part during routine maintenance or system diagnostics.

This switch is intended for commercial appliance applications where precise pressure actuation is required to protect or control system operation. It is suited for environments where reliable cut-in and cut-out pressure control is critical to maintaining consistent equipment performance. The CI-80 CO-55 rating identifies the specific pressure differential at which the switch transitions states, making correct replacement selection important for proper system behavior.

Key Features

• SPST configuration provides a single switching circuit for straightforward pressure control
• Cut-in pressure of 80 psi and cut-out pressure of 55 psi for defined actuation points
