Standards & Certifications
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.

Distinctive Characteristics
Actual Size
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.

Vertical Mounting PC
Single Pole and

Rocker switches with vertical and right angle terminals must be mounted so that extension of the PC board beyond the top of the switch
housing does not interrupt rocker movement, in turn causing incomplete switching operation.
The MAXIMUM limit of the PC board extension is .051” (1.3mm), as illustrated below.
This precaution does not apply to the double pole switch with right angle terminals due to the extra width of the switch allowing the
rocker to clear the PC board.
