Distinctive Characteristics
Pushbuttons
Double flatted bushing prevents rotation in panel and increases
stability.
Programmable Illuminated PB
Totally sealed construction, achieved with combination of an
interior o-ring, a seal between the frame and base, plus insert
molded terminals, prevents contact contamination and allows
automated soldering and cleaning.
Break-before-make contact timing with sliding
contact mechanism.
Metal bushing and frame/bracket provide
durability.
G
Tactiles
Slides
Panel seal, achieved with use of optional
exterior o-ring, conforms to IP67 of IEC60529
Standards.
Rotaries
Keylocks
Positive detent mechanism for distinct feel and audible
feedback.
Tilt
High contact reliability achieved by the self-cleaning
contact mechanism.
.100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to
standard PC board grid spacing for straight and right angle mounting.
