Tact switches for automotive

“As an automobile safety consideration, input switches inside vehicles are increasingly integrated into the steering wheel area for drivers to operate without taking their eyes off the road,” according to the company. “Moves to place driving automation controls at drivers’ fingertips, too, are also picking up pace given that Level 2 and Level 3 automated driving, the focus of current commercialisation efforts, require switching between human driver and automated driving system modes depending on the circumstances, an action that makes use of switches and must be performed quickly in an emergency.”

1.04mm travel is at the longer end of the middle stroke range, and 5N is a relatively heavy operating force – with the aim of enhancing clarity in use and helping to prevent accidental operation.

The part, to be know as SKSUBBE010 also incorporates a pre-stroke design (see graph) to help to prevent rattling against other parts when integrated into end products. They are sealed to “IP67-equivalent dust and water resistance”.

The SKSU series has mounting compatibility with the company’s SKTQ series, giving customers a choice of feel without modifying PCBs. “Alps Alpine has developed and manufactured around 30 main types of tact switch for automotive use. Through ongoing additions to an already diverse feel variety, Alps Alpine will attend to the needs of the market and customers while contributing to a more comfortable experience for vehicle users,” according to the company.

Applications are expected in the steering wheel area and on-board units for centre console panels, as well as car audio and car navigation units.

Mass production is scheduled for April 2020.
