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).

See Profile A in Supplement section. Manual Soldering: See Profile A in Supplement section. Cleaning: Automated cleaning. See Cleaning Specifications in Supplement section. Standards & Certifications Flammability Standards: UL94V-0 actuator & base UL Recognition or CSA Certification: 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.
