Ultra-Thin Process Sealed Tactiles
Series JF
Distinctive Characteristics
Extremely low profile of .224” (5.7mm) from PCB to top of switch.
Red, green, or yellow LED with spot or full face illumination.
Rubber seal construction prevents contact contamination
and allows automated soldering and cleaning.
Minimal operating force and short stroke
permit light touch operation.
Dome contact gives crisp tactile and
audible feedback to positively indicate
circuit transfer and assures high reliability
and long life.
Space saving body dimensions provide for compact,
side-by-side mounting on a standard grid.
Crimped terminals ensure secure mounting and prevent
dislodging during wave soldering.
Terminal spacing conforms to standard .100” (2.54mm) PCB grid.
Matching indicator available and shown at the end of Section M.
Actual Size
Common Bus Matrix
These single pole, single throw switches can be used in a keyboard
matrix and, using strapped terminals, achieve a common bus electri-
cal configuration on a single-sided PC board.

PCB Processing
Soldering:
Cleaning:
Wave Soldering recommended. See Profile A in Supplement section.
Manual Soldering: See Profile A in Supplement section.
Automated cleaning. See Cleaning specifications in Supplement section.
Switches should not be operated or have any pressure on the actuators during cleaning.
Full face illuminated models suitable only for bottom board spray wash to avoid contamination
of the 2-layered actuator, which may compromise the aesthetics.
Standards & Certifications
UL Recognition
or CSA Certification:
The JF 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 the switch. The electrical specifications shown 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.
