Features & Applications

HP0315AFKP2-S is a HP03 series of square SPST 1.6 N 6 mm gull wing surface mount tactile switch. Heat resistant resin body meets lead-free solder processing requirements and UL flammability rating of 94 V-0. Stick-tube and tape-reel packaging allow rapid automated placement of devices.

Gold plated contacts available for very low voltage/current applications offer advantages of little or no oxidization or sulfurization and stable contact resistance. Gull-winged terminals ensure mechanical stability during soldering and simplified solder joint inspection. Insert molded terminals lock out flux, solvents, and other contaminants and allow automated soldering. 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 .0039” (0.10 mm). (Additional coplanarity details in Terms and Acronyms in the Supplement section.
