Installation
Mounting: It is recommended that the body of models for upright mounting without bracket be fastened to a
panel or similar support for protection of solder joints from mechanical stress.
Coplanarity: See specifications in Terms & Acronyms in Supplement section.
Processing
Soldering: Reflow Soldering Recommended. See Profile B in Supplement section.
Manual Soldering: See Profile B in Supplement section.
Cleaning: Automated cleaning. See Cleaning specifications in Supplement section.
Standards & Certifications
Flammability Standard: UL94V-0 actuator, case & base
The G3B 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.

Distinctive Characteristics
Ultra-miniature size allows high density mounting, and extremely light weight
of 0.6 gram makes these switches ideal for handheld equipment.
Tape-reel and stick-tube packaging allow rapid automated
placement of surface mount devices. Tape-reel packaging
meets EIA-481-D Standard.
Heat resistant resin used for housing, base, and plunger
allows vapor phase and infrared convection reflow
soldering.
Combination of design features achieves total seal and
allows automated processing techniques, including flux
cleaning procedures: one-piece bushing and housing,
rubber seals surrounding actuator and base, epoxy at
joint of case and base, and molded-in, epoxy-sealed
terminals.
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.)
Gull-wing terminals provide mechanical stability during soldering
and simplified solder joint inspection.
Coplanarity: all considered surfaces must lie between two parallel planes that
area maximum distance apart of .0059” (0.15mm). (Additional coplanarity
details in Terms and Acronyms in the Supplement section.)
