Pressure switch AWTools AW10205 for air compressors 230V, 1/4" inlet, single input

AWTools AW10205 is a pressure switch designed for control of air compressors operating from a 230V supply. The device features a single pneumatic input with a 1/4" threaded inlet and internal switching contacts that monitor system pressure and actuate the compressor motor when the preset pressure thresholds are reached. Intended for workshop and domestic compressor systems, the switch automates start/stop cycles and provides basic overpressure protection by interrupting power at the upper limit.

Advantages

The AWTools pressure switch offers a compact mechanical solution for reliable pressure monitoring and motor control without additional electronics. Its 1/4" threaded inlet allows straightforward installation to standard compressor fittings. Rated for 230V operation, the switch is compatible with common single-phase compressor motors and provides repeatable switching action for consistent pressure regulation. The built-in contacts reduce the need for external relays or control modules in simple compressor installations.

Suitable for

• Small workshop and garage air compressors
• Home compressor systems for DIY tasks and inflating
• Replacement of worn or faulty pressure switches on compatible compressors
• Basic compressor automation where electronic controllers are not required

Key specifications

• Supply voltage: 230V AC
• Pneumatic inlet: 1/4" threaded connection
• Input type: single pneumatic input
• Switching: mechanical internal contacts for motor control
• Application: on/off control based on adjustable pressure thresholds

How to use

Mount the pressure switch to the compressor tank or manifold using the 1/4" threaded inlet, ensuring a sealed connection and appropriate thread sealing tape or sealant as required. Connect the electrical terminals to the compressor motor circuit following wiring diagrams provided with the compressor or the switch manufacturer’s instructions, and ensure the supply is 230V AC. Adjust the cut-in and cut-out pressure settings as needed according to the compressor and tool requirements, then restore power and observe a few start/stop cycles to confirm correct operation.

Usage recommendations

Install the switch in a dry, vibration-minimized location and follow electrical safety practices: disconnect mains power before wiring, use appropriate cable cross-sections and protective devices, and verify pressure settings within the compressor’s rated limits. Periodically inspect the switch for corrosion, secure mounting, and correct operation; replace if mechanical contacts show wear or erratic switching occurs.
