ALPS has introduced the SKTH series TACT switch aimed at automotive electronics such as keyless entry systems and car audio systems.

SKTH series

For durability and reliability, the SKTH series uses metal contacts whose shape and material were optimised using mechanical design and material technology built up by ALPS over many years. These metal contacts, combined with an original sealed contact structure, realise both an excellent operating feel and an IP6x dust resistance rating.

The part materials and internal structure have been optimised for high strength, achieving an operating life of 200,000 cycles, twice as long as the life of earlier models, noted the company. Measuring 3.5 x 3.2 x 1.8mm with 0.12mm of travel, the switches are available with an operating force of 1.4N or 3N, and a stem length of 1.8mm or 2.5mm.
