Tokyo, Japan The next generation of SPED series push switches from ALPS Electric Co., Ltd. features near-silent operation, smooth operational feel, and a thinner profile for lamps in car cabin interiors.
The SPED3 switches, which measure 18 (W) x 14 (D) x 20.7-mm (H), are rated at 1 amp, 14.5 Vdc. Travel is 3.8 mm. Operating life is rated at 30,000 cycles.
ALPS developed the SPED3 Series with a very quiet mechatronic operation, which is due to the company's proprietary ratchet cam construction. Very little impact sound is generated as the cam connects to a slide when the switch is pushed due to an embedded damper spring in the movable slide component, said the company.
In addition, the ridges of the cam are smoothed out, making very little sound as the slide and cam meet when the slide returns to its original position.
The new design also contributes to cost reductions at automakers and cabin equipment manufacturers. The company said similar conventional products in the industry must be pushed six to eight times to inspect the internal contact points that move with the cam and revolving internal components. In comparison, the SPED3 Series reduces the number of pushes by half, to four times, contributing to cost reductions during their equipment operation inspection processes.
Samples are available now. The sample price for the SPED3 is $1.29.
