ARO 104196 Adjustable Pressure Switch 500psi 125Vdc

ARO 104196 Adjustable Pressure Switch is a compact, field-adjustable control device from Ingersoll Rand’s ARO line that detects system pressure and triggers a switch to control a compressor or other pneumatic equipment. The family is available in several connector configurations, including switch-only (104196), 104196-CHW (with molded cable connector), 104196-CSN (with strain-relief connector), and 104196-CDW (with a 1/2" conduit connector), so you can match wiring and mounting to your installation. The unit is rated for operation on 125 V DC, making it suitable for DC-powered control circuits in industrial pneumatic setups. Within the CHW variant, a typical sensing range is listed as 20–100 psi with connector, while other suffixes align with different ranges and connector options, all of which are designed to be used with single- or three-phase piston air compressors and similar equipment. The 104196 is explicitly described as a user-adjustable pressure switch, enabling you to set the activation pressure to fit your specific system requirements and providing automatic start/stop control as pressure travels to the programmed setpoint. In practice, this makes the 104196 suitable for OEM or service-replacement use in industrial compressed-air applications where a compact, reliable, DC-rated pressure switch is required to manage compressor cycling and protect pneumatic circuits.
