Ultra-Miniature Fully Illuminated Plungers
Series GB
Distinctive Characteristics
Fully illuminated plunger for highly visible status indication
with single color LED in red, green, or amber.
Ultra-miniature size allows high density mounting,
and extremely light weight makes these switches
ideal for handheld equipment.
Totally sealed body construction prevents
contact contamination and allows time- and
money-saving automated soldering and
cleaning. Insert-molded terminals lock out
flux, solvents, and other contaminants.
Award-winning STC contact mechanism
with benefits unavailable in conventional
mechanisms: smooth, positive detent actuation,
increased contact stability, and unparalleled
logic-level reliability. (Additional STC details
in Terms & Acronyms; see Supplement section.)
.100” x .100” (2.54mm x 2.54mm) terminal
spacing conforms to standard PC board grid
spacing. Round terminals facilitate easier
through-hole mounting on PC boards.
Nonilluminated pushbuttons available and shown
in the Pushbutton section.

PCB Processing
Soldering:
Wave Soldering recommended. See Profile B in Supplement section.
Manual Soldering: 4 seconds maximum @ 390°C maximum
Cleaning:
Automated alcohol based cleaning recommended, 5 minutes maximum. Do not use high-purity
alcohol (50% alcohol or more) or organic solvent. High alcohol solution can damage clear plastic.
See Cleaning specifications in Supplement section.
Standards & Certifications
UL Recognition
or CSA Certification:
The GB Series illuminated 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.

LED COLORS & SPECIFICATIONS
LEDs are an integral part of
the switch and not available
separately. The electrical speci-
fications shown are determined
at a basic temperature of 25°C.
If the source voltage exceeds the
rated voltage, a ballast resistor
is required.
The resistor value can be cal-
culated by using the formula in
the Supplement section.
