CX-42 Description

Short technical summary and product information.

The Mercoid CX-42 Series CX Compressor Pressure Switch is engineered for direct control of pumps and motors, making it ideal for regulating tank pressure on small air compressors. This switch offers a pressure range of 35-150 psig with an adjustable deadband of 30-40 psig. It incorporates a 20 Amp SPST normally closed switch for reliable operation.

 

Designed for ease of installation, the CX-4 models include a 4-port connection block, allowing for the optional installation of a pressure gauge. The set point and deadband are easily adjustable via screw terminals located inside the cover. These switches can be mounted in any orientation, providing flexibility in application.

 

Additional features include an unloader valve to prevent compressors from starting under load and an auto/off disconnect lever for manual load cutoff. A test button inside the housing allows for manual load activation when the lever is in the off position. The wetted materials are aluminum alloy, and it has a maximum temperature limit of 60°C (140°F).
