6mm Process Sealed SMT Tactiles Series CB3 Distinctive Characteristics 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-481-2 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.)

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.
