Position Switches for potentially explosive atmospheres

An Ex d-certified snap-action switch lies at the core of the Ex-approved switches. This switch with protection class flameproof encapsulation can be used in zones 1, 2, 21 and 22. The snap-action switch has two galvanically isolated contacts, one NC contact and one NO contact. BERNSTEIN proposes the ENM2 and GC series as position switches
for potentially explosive atmospheres.
