Ultra-Miniature Process Sealed SMT Toggles
Series G3T
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-481-2 Standard.
Heat resistant resin used for housing, base, and
lever 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 are a
maximum distance apart of .0059” (0.15mm). (Additional coplanarity details in Terms
and Acronyms in the Supplement section.)

Standards & Certifications
UL Recognition
or CSA Certification:
The G3T Series toggles 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.
