Interstate Pneumatics LF10-4H Pressure Switch - 1/4 inch FPT Four Port Bend Lever Switch 20 Amps 85-125 PSI Fits Dewalt Hitachi Emglo Makita Porter Cable Ridgid Rolair Air Compressors

The Interstate Pneumatics LF10-4H is a 4-port air compressor pressure switch designed for use with single-stage or two-stage compressors that operate up to 125 PSI. It includes an unloader control valve and a bend lever switch. The built-in metal lever allows you to easily turn the switch on or off, while the unloader valve, located on the side, helps release head pressure from the compressor pump for a smooth, load-free startup. If your compressor doesn’t require an unloader valve, it can be left disconnected without affecting the switch’s performance. Compatible with most Air Compressors such as DeWalt / Hitachi / Emglo / Makita / Porter Cable/ Ridgid / Rolair and many more.

 

The four-port manifold allows flexible mounting in any direction and provides the option to add a relief valve, gauge, or additional air outlet ports. This pressure switch is pre-set to activate the compressor at 35 PSI and deactivate it at 150 PSI. You can adjust these settings within the factory’s specified minimum and maximum pressure ranges as seen below.
