The WIKA diaphragm pressure switch these is high-quality mechanical pressure switches have been developed especially for safety-critical applications. The great advantage of mechanical pressure switches is that no supply voltage is required for the switching process. In production, the switches are traced by quality assurance software at every step and subsequently are 100 percent tested.

Robust switch enclosure from aluminium alloy, IP66, NEMA 4X
Switch point repeatability less than 1 %
