Distinctive Characteristics
Ultra-miniature size allows high density mounting, and extremely
light weight of 0.25 gram makes these switches ideal for
handheld equipment.
Totally sealed body construction prevents contact
contamination and allows time-and money-saving
automated soldering and cleaning.
Award-winning STC contact mechanism with
benefits unavailable in conventional mech-
anisms: 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. Round terminals
facilitate easier through-hole mounting on
PC boards.
Matching indicators available and shown at the
end of Section M.
