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.
