SMT Switches Developed To Replace PCB Jumper Pins

The replacement of traditional jumper pins, reportedly one of the last remaining non-surface-mount components found on pc boards, is the promise made for new SMT switches having a single-pole, double-throw (SPDT) contact arrangement. The compact CJS jumper switches measure just 5.4 x 2.5 x 2.5 mm, have a -40°C to +85°C operating temperature range, and are available with J-hook or gull-wing leads and with or without a neutral detent. The low-profile SPST switches can be mounted and soldered in the same way as other SMT components—the devices can withstand reflow solder temperature of 240°C. Their housing and cover are made of UL-94V-0-compliant materials, while the slider, fixed contacts and terminal pins are based on a gold-plated, copper alloy. The CJS jumper switches cost as little as $0.35 each/75,000 for washable versions sealed with tape and $0.31 for non-sealed types.
