Distinctive Characteristics

Available in flat frame and bracketed PC mounting types.
Over-center actuator block and plunger design gives crisp actuation with clear indication of circuit status; this design also diminishes sparking and increases operating life.
Guide interlocked with actuator block prevents window locking and maintains correct plunger alignment to assure contact stability.

Antijamming design protects contacts from damage due to excessive downward force on the actuator.
High internal barriers between poles and insulating sheet between case and actuator block give added protection to contacts.
Specially composed silver alloy contacts for power applications or gold contacts for logic level applications give high contact reliability.

Prominent external insulating barriers increase insulation resistance and dielectric strength.
Epoxy sealed terminals prevent entry of flux, solvents, and other contaminants.
Clinching of frame to case well above base and terminals provides 1,500V dielectric strength.
