UL94V-0 actuator & base
The CB3 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.

6mm Process Sealed SMT Tactiles
Series CB3
Toggles
.244” (6.2mm) square body allows compact mounting.
Heat tolerant resin used for actuator and base
meets UL flammability rating of 94V-0 and
maintains switch reliability through vapor
phase and infrared convection reflow
soldering.
Dome contact gives crisp tactile feedback
to positively indicate circuit transfer and
assures high reliability and long life –
more than 100,000 operations.
Gull-winged terminals ensure mechanical stability
during soldering and simplify solder joint inspection.
Insert molded terminals lock out flux, solvents, and other contaminants.
Packaged in tape-reel or partitioned tray. Tape-reel packaging meets EIA-481-D
Standard.
Coplanarity: all considered surfaces must lie between two parallel planes that are
a maximum distance apart of .0059” (0.15mm). (Additional coplanarity details in
Terms and Acronyms in the Supplement section.)
