Standards & Certifications
The AB Series pushbuttons 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.

C
Specifically developed for logic-level applications.
Totally sealed body construction prevents contact contamination
and allows time- and money-saving automated soldering
and cleaning.
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.
