A built-in unloader valve bleeds off head pressure each time the switch shuts off, so the motor restarts under no load — and a front-mounted On\/Off (Auto\/Off) lever lets you run the compressor automatically or shut it down without unplugging it. It's a popular direct replacement switch for a wide range of single-phase reciprocating compressors.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Lefoo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Mechanical air compressor pressure switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure ranges available:\u003c\/strong\u003e 95–125 PSI and 140–175 PSI (factory preset, field-adjustable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort configurations:\u003c\/strong\u003e Single-port or 4-port manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir connection:\u003c\/strong\u003e 1\/4\" FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnloader valve:\u003c\/strong\u003e Integrated, for unloaded restarts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e Front On\/Off (Auto\/Off) lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e Single-phase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eUsed as a replacement or upgrade control on piston\/reciprocating air compressors, portable and stationary shop compressors, and similar single-phase pump-driven systems.
