K5G and K5A2 switches

C&K Components has added two new devices to its family of K5 Series of snap-acting key switches that feature silver- or gold-plated dome inserts for enhanced user feel, provide excellent tactile feedback, and are housed in small, low profile packages.

The K5G switch is a double action SPST switch measuring only 8.2mm x 8mm x 6mm. The switch has a dual functionality design, streamlining equipment design and making it suitable for multifunction equipment. The momentary action switch features a mean operating force of 3.7N for the first stroke, and 6.5N for the second stroke. Travel is 0.5mm and 0.85mm for the first and second strokes, respectively. The K5G switch features an operational life of 30,000 actuations, and is designed for use in car window and sun-roof controls, as well as multifunction controllers.

The momentary action, normally open K5A2 key switches are even lower profile, measuring just 8.2mm x 8mm x 4.5mm. Mean operating force is 5.5N, with a 6N version available. Electrical travel is 0.5mm (0.1mm), with an operational life of 50,000 actuations. The K5A2 switch is specified for use in automotive, computing and networking equipment.

"Along with superior tactile feel, the K5G and K5A2 switches provide excellent acoustic qualities," said Gustavo Jimenez, product manager for C&K. "Coupled with our large production and inventory capacity, we are able to satisfy customer's design requirements as well as immediate volume production demands."

Both the K5G and K5A2 switches are available on tape and reel packaging for automated assembly. Typical pricing for the K5G and K5A2 switches ranges from $0.97 to $1.50 in minimum order quantities of 1,200 pieces.
