C&K Components has enhanced its KMT Series tactile switches with halogen-free materials. Measuring just 2.6mm x 3.0mm x 0.65mm, with a 0.45mm body height, the ultra-miniature tactile switch now provides customers with a means of meeting miniaturization and ultra high reliability specifications, while also conforming to all environmental requirements.

“Halogen-free plastics are fully recyclable, so as environmental issues continue to play a large role in all component and end product designs, halogen-free plastics enable customers to tout their “green” commitment,” said Jerome Smolinski, senior product manager for C&K Components. “This device is also one of the industry’s smallest top-actuated tactile switches available, allowing it to be specified for use in a multitude of space-constrained applications including hearing aids, mobile phones, MP3 accessories and Bluetooth headsets.”

Featuring an integrated push plate and a ground pin option for ESD protection, the SPST NO halogen-free switches are available with gold and silver plating options and are specified to 150,000 electrical and mechanical life cycles. Actuator height is 0.2mm, and travel is 0.13mm.

The integrated actuator allows for simpler button design while yielding an excellent tactile ratio of 30% minimum, providing sharp feedback. Actuation force options are 1.6N (tactile ratio 30%) for mobile devices and 1.0N (tactile ratio 10%) for hearing aids and headsets. Operating temperature ranges from -40°C to +85°C.
