A must-have switch

Factory-correct reproduction

These authentic reproduction switches mount to the “VIR” (valve in receiver) and acts as a safety shut-off for the compressor in the event of a leak, which is signaled by low pressure. The binary pressure switch is an excellent upgrade for cycling systems and features the correct terminals for a hassle-free connection to original wiring.
