Standards & Certiﬁcations

Flammability Standards: UL94V-0 rated case & base

The JB Series tactiles 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.

Series JB Toggles Low Profile Process Sealed Tactiles Rockers Distinctive Characteristics Pushbuttons Special bracket for right angle mounting provides added design variations. Programmable Illuminated PB Higher operating force type provides more pronounced operating feel. Rubber seal construction prevents contact contamination and allows automated soldering and cleaning. Choice of dimensions from PCB to top of cap allows design flexibility.
