Standards & Certifications

Flammability Standards: UL94V-0 actuator, case, & base

The GB2 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.
