Indicators
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.

Ultra-Thin Process Sealed Tactiles
Series JF
Toggles
Extremely low profile of 5mm from PCB to top of switch.
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.
Wide choice of body shapes and colors.
Crimped terminals provide a spring type action to ensure
secure mounting and prevent dislodging during wave soldering.
Space saving body dimensions provide for compact, side-by-side mounting
on a standard grid.
Terminal spacing conforms to standard .100” (2.54mm) PCB grid.
