Standards & Certifications
The GB 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.

Totally sealed body construction prevents contact
contamination and allows time- and money-saving
automated soldering and cleaning.
.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.
