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.)
