PCB Processing
Soldering: Wave Soldering recommended. See Profile A in Supplement section.
Manual Soldering: See Profile A in Supplement section.
Cleaning: 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
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.

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.
Actual Size
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.
