6101-0021 (HERGA)

The 6101-0021 is a 10 to 50-inch H?O panel or chassis mount SPDT Pressure Switch with phosphor bonze with gold inlay contacts. The operation is identical-fluid pressure acting against the diaphragm causes the cantilevered contact blade to deflect. The amount of deflection is a function of the contact thickness and the pressure. The contact blade deflects until it contacts the sharp points of the fixed adjustment blade, completing an electrical circuit. The relative position of the contact blade and the adjustment blade is determined by the adjustment screw, which moves the relatively rigid adjustment blade toward the contact blade.
