Process Sealed Subminiature Toggles
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 contents.)
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.
Toggle option in antistatic material available for
dissipating electrostatic discharges.
Matching indicators available and shown at the end of Section M.

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