Questions about this product
- Will this pressure switch work with my existing air compressor and motor?
- It fits most workshop air compressors that use standard 1/4-inch NPT pneumatic fittings. For electrical compatibility, it supports dual-voltage AC motors rated up to 1/2 horsepower. Always check your motor's current draw against the switch's limits before installing.
- How do I connect my pressure gauge and safety valve to this switch?
- The integrated 4-port manifold lets you attach gauges and safety valves directly to the switch. Each port uses standard 1/4-inch NPT threads to ensure a tight, leak-free connection. You can wire your power lines easily using the internal screw terminal block.
- Can I adjust this switch to run at a higher pressure than 120 PSI?
- This switch is pre-set to start your compressor at 90 PSI and stop it at 120 PSI. Although the aluminum housing handles up to 150 PSI, you should not adjust these factory limits. Changing the pressure range manually can overload your motor and void the warranty.
