The HornBlasters Weatherproof Pressure Switch with Relay dual pack gives you two 110-150 PSI switches for $34.99, which puts each one under $18. Every switch is fully encased and sealed with weatherproof sealant, and the built-in relay keeps installation simple with no extra wiring needed.
The switch turns your compressor on when tank pressure drops to 110 PSI and shuts it off when it hits 150 PSI.
Check your compressor's amp draw before you buy. These switches are rated for a max of 10 amps. If your compressor pulls more than that, use the switch to trigger an external relay instead of running the compressor through it directly.
