Low Profile Process Sealed Tactiles
Series JB
Distinctive Characteristics
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.
Actual Size
Common Bus Matrix
These single pole, single throw switches can be used in a key-
board matrix and, using strapped terminals, achieve a com-
mon bus electrical configuration on a single-sided PC board.

Standards & Certifications
Flammability Standards:
UL Recognition
or CSA Certification:
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.

LED COLORS & SPECIFICATIONS
LEDs are supplied as an integral part of
illuminated devices and are not available
separately.
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 volt-
age, a ballast resistor is required.
The resistor value can be calculated by using
the formula in the Supplement section.
