C&K Introduces Compact Dual-Circuit Tact Switch for Automotive, Industrial and Medical Applications

First dual-circuit, IP67-rated tactile switch in a small PCB-mount package

NEWTON, Mass., January 16, 2019 – C&K, one of the world’s most trusted brands of high-quality electromechanical switches, announces the launch of a dual-circuit technology tact switch as a significant addition to its extensive KSC range of tactile switches.

The new KSC-DCT tact switches offer SPDT NC-NO dual-circuit functionality that provides two outputs from a single input. Housed in a tiny 6.2 mm x 6.2 mm x 2.9 mm PCB-mount package, the silicone 70SH actuator included in the package extends the height to 5.2 mm above the PCB surface for easy operation and easier integration through pre/post travel.

Rated for 300,000 operations, the new switches require an operating force of 4.75 N and provide a nominal travel distance of 0.85 mm. Incorporating C&K Switches’ industry-recognized haptics, the KSC-DCT switches provide excellent levels of feedback when pressed.

The new switches are IP67 sealed and operate over the temperature range -40°C to +85°C, making them suitable for use in harsh environments – especially those found in automotive, industrial and medical applications.

“The KSC-DCT tact switch is an important addition to our comprehensive range of KSC tact switches,” said Jérôme Smolinski, Global Product Manager, C&K. “It is the first SMT tact switch with an IP67 rating in a 6.2 mm x 6.2 mm package to offer SPDT functionality. In fact, it is the smallest and lowest-cost alternative to snap switches currently available.”

The lead-free reflow-compatible KSC-DCT switches are supplied in reels of 1,000 pcs for easy automated pick-and-place processing. For design engineers, 3D models in a variety of file formats are available from the C&K website.
