Distinctive Characteristics
Pushbuttons
Available in flat frame and bracketed PC mounting types.
Programmable Illuminated PB
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.
Keylocks
Antijamming design protects contacts from
damage due to excessive downward force
on the actuator.
Specially composed silver alloy contacts for
power applications or gold contacts for logic
level applications give high contact reliability.
Tactiles
H
Slides
Rotaries
High internal barriers between poles and
insulating sheet between case and actuator
block give added protection to contacts.
Prominent external insulating barriers increase
insulation resistance and dielectric strength.

Accessories
Indicators
Clinching of frame to case well above base and terminals provides
1,500V dielectric strength.
Tilt
Epoxy sealed terminals prevent entry of flux, solvents,
and other contaminants.
