Distinctive Characteristics
Subminiature size saves space on PC boards.
Specifically developed for logic-level applications.
Antistatic superstructure, consisting of the carbon impregnated
bushing and the support bracket, prevents static discharge
to the contacts. Static electricity from an operators touch
travels from actuator through the bushing and bracket to
the PC board.
Locking lever mechanism offered as a toggle option.
Optional threaded, 6mm diameter bushing for
panel seal mounting meets IP65 of IEC60529
specifications (similar to NEMA 4 and 13).
Totally sealed body construction prevents
contact contamination and allows time-
and money-saving soldering and cleaning.
Epoxy sealed terminals lock out flux and
other contaminants.
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.)
.100 x .100 (2.54mm x 2.54mm) terminal spacing
conforms to standard PC board grid spacing.
