Standards & Certifications
Indicators
Flammability Standards:
UL94V-0 actuator, case, & base
The GB2 Series pushbuttons have not been tested for UL recognition or CSA certification.
These switches are designed for use in a low-voltage, low-current, logic-level circuit.
When used as intended in a logic-level circuit, the results do not produce hazardous energy.

Actual Size
Touch
.100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to
standard PC board grid spacing for straight and angle mounting.
Tilt
Molded-in, epoxy sealed terminals lock out flux and other
contaminants.
Tactiles
Award-winning STC contact mechanism with benefits
unavailable in conventional mechanisms: smoother,
positive detent actuation, increased contact stability
and unparalleled logic-level reliability. (Additional STC
details in Terms & Acronyms; see Supplement section.)
Slides
Rotaries
Extremely thin size allows high density PCB mounting
and makes these switches ideal for handheld equipment.
Keylocks
Black, white, and red snap-on caps available.
Programmable Illuminated PB
Pushbuttons
Unique, off-center actuator allows high density setup and easy
actuation while avoiding accidental operation in compact
environments.
