C&K Components' momentary-action tactile switches tout low profile, tiny footprint



PTS 540 Series switches

C&K Components, a leading international supplier of tact switches, toggle and rocker switches, and smart card interconnect devices, has developed a series of surface mount ultra low profile top-actuated tactile switches with extended operating lifecycles up to 500,000. The switches measure just 3.7mm x 3.7mm with a board-mounted profile of 0.35mm.

The PTS 540 Series tactile switches are RoHS-compliant SPST (single-pole, single-throw) top-actuated surface mount devices with a selection of operating force ratings and operating lifecycles (160gf ±50; 500,000 cycles, black casing, and 230gf ±50; 200,000 cycles, gray casing) with a travel distance of 0.15mm ±0.1mm and bounce time of less than 10ms. Contacts are rated for 50mA (max) and 12VDC (max). Operating temperature range is -30°C to 85°C.

"The PTS 540 Series switches are designed to save space, especially in the profile dimension, within today's miniaturized portable electronic devices, such as MP3 accessories, Bluetooth headsets and remote control devices," said Jerome Smolinski, senior product manager at C&K Components. "With a choice of actuating forces and operational lifecycles up to 500,000, they are well-suited for a wide variety of rugged consumer devices."

The PTS 540 Series switches are sold in 10,000-piece tape-and-reel packaging. Engineering samples are currently available.
