Process Sealed Subminiature Rockers
Series A
Distinctive Characteristics
Subminiature size saves space on PC boards.
Specifically developed for logic-level
applications.
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
mechanisms: smoother, positive
detent actuation, increased contact
stability and unparalleled logic-level
reliability. (Additional STC details in
Terms & Acronyms; see Supplement
section.)
Molded-in, epoxy sealed or ultrasonically
welded terminals lock out flux, solvents,
and other contaminants.
.100” x .100” (2.54mm x 2.54mm)
terminal spacing conforms to standard PC
board grid spacing.
Matching indicators available and shown at the
end of Section M.

Standards & Certifications
UL Recognition
or CSA Certification:
The A Series rockers 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.
