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.

Illuminated Low Profile Process Sealed Tactiles
Series JB
Toggles
Choice of dimensions from PCB to top of cap adds to design flexibility. Bright, full-face illumination with red, green, or yellow LEDs for attractive, functional panel layouts. Higher operating force type provides more pronounced operating feel. Dome contact gives crisp tactile feedback to positively indicate circuit transfer and assures high reliability and long life of up to 5,000,000 operations. Rubber seal construction prevents contact contamination and allows automated soldering and cleaning. Slanted terminals provide a spring type action which ensures secure mounting and prevents dislodging during wave soldering. Molded-in terminals are part of the sealed construction which allows automated soldering and cleaning. Terminal spacing conforms to standard .100” (2.54mm) PCB grid.

LED polarity markings are on the bottom of the switch. The electrical specifications shown here are determined at a basic temperature of 25°C. If the source voltage exceeds the rated voltage, a ballast resistor is required. The resistor value can be calculated by using the formula in the Supplement section.
