Industrial 201806GS Pressure Switch With Unloader Valve

Briggs & Stratton 201806GS pressure switch with unloader valve is an OEM replacement designed for Brute and Troy-Bilt air compressors, delivering a 95 psi start (cut-in) and 125 psi stop (cut-out) with an adjustable range within that window. It is a four-port assembly with 1/4" NPT connections and a 1/4" quick-connect fitting for the unloader line, and it uses a push-pull on/off control for manual operation. Electrical ratings are 20 amps at 120 VAC and 12 amps at 240 VAC, suitable for common workshop compressors. The unit measures about 5.80 inches long, 4.10 inches wide, and 2.65 inches tall, and weighs roughly 0.78 lb, making it a compact OEM replacement that can be swapped in without major modification. Verified compatibility includes Briggs & Stratton Power Products, Brute, and Troy-Bilt units that use the 201806GS switch, preserving the standard unloader function when the compressor stops and restarts. As an original equipment part, it maintains the same push-pull control and wiring layout as the factory switch, helping restore normal cycling and safe pressure management on Briggs & Stratton-powered compressors.
