Single Pressure Switches

Designed for controlling pressure with higher current capacity. These switches are used widely in steam cleaners, steam irons, and other pressure control systems. It provides SPDT contact and Series A9 Pressure Switches utilize high-quality miniature snap-action switches.

Proven reliable for controlling automatic water systems. These switches are very popular for use on water well pumps and pumping systems. The set point and deadband are both easily adjustable via screws inside the cover. For ease of installation, the switches come with a 1/4" female NPT process connection and can be mounted in any orientation.

Same rugged construction as used in Series 1000W plus explosion-proof design are combined in this unit. UL listed for Class I, Groups A, B, C and D; Class II, Groups E, F and G. Bellville spring movement permits mounting of control in any position and helps prevent contact chatter. Features Visible Setpoint, Fixed Deadband, and Ranges to 1400psi.

Extremely rugged construction provides excellent reliability in chemical, petroleum and industrial plants and provides high overpressure protection. Bellville spring movement permits mounting of control in any position and helps prevent contact chatter. Features Weatherproof Housing, Visible Setpoint, Fixed Deadband, and Ranges to 1400 psi.

Wetted materials of 316 SS and fluorocarbon ensure great chemical compatibility with a wide range of process media. The open case style is perfect for panel mounting applications like pump skids. Field installable weatherproof enclosure is available in polycarbonate offering a low cost weatherproof switch.
