Standards & Certifications
Flammability Standards: 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.

Sealed construction prevents contact contamination and allows automated
soldering and cleaning.
.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.)

PACKAGING
RTape-Reel (packaged to EIA-481-D standard)
Switches must be ordered in 1,000-piece increments
when tape-reel packaging is selected.
Partitioned Tray
If less than 1,000 pieces are ordered, the switches are
packaged in a partitioned tray. No code is required.

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.
X-Y Matrix
These single pole, single throw switches can be ar-
ranged on a single-sided PC board matrix with
strapped terminals to achieve an X-Y type electrical
interconnection.
