Condor MDR11 26 Amp Heavy-Duty Air Compressor Pressure Switch
The Condor MDR11 is a heavy-duty, two-pole pressure switch that automatically starts and stops a single-phase air compressor as tank pressure rises and falls. Rated for a full 26 amps at 240V (UL/CSA) with a 3 HP motor switching capacity, it stands up to the demanding duty cycles of shop and industrial compressors, while its rugged NEMA 1 steel-flange housing resists vibration and daily wear. Both the pressure range and the differential are fully adjustable, so one switch can be dialed in to your exact cut-in and cut-out targets.
Choose your configuration below: factory pressure range (80–100, 100–125, 120–150, or 140–175 PSI), a 1-port or 4-port manifold, and the control features you need — a manual On/Off lever, a compression-style unloader valve that bleeds head pressure for easy restarts, or both.

Applications
An ideal replacement or OEM control for reciprocating (piston) air compressors in automotive shops, workshops, and light industrial settings. The On/Off lever gives you a convenient manual disconnect, while the unloader valve releases trapped head pressure so the motor restarts against no load — extending motor life and preventing hard starts.
Backed by Condor’s reputation for dependable compressor controls, the MDR11 26-amp pressure switch is a direct, durable replacement for worn or failed switches. Select the pressure setting, port count, and function that match your compressor to keep it cycling safely and automatically.
