Development of New TACT Switch for Automobiles by ALPS Electric

March 4, 2010 · Filed Under Trendy Products 

Alp SKPR TACT SwitchAutomobile manufacturers have increasing incorporated a variety of switching components on to the steering wheel of the vehicle rather than on the hard to reach instrument panels. This sort of design previously was primarily targeted at luxury automobiles, allowing the driver to directly operate on-board devices such as audio equipment and air-conditioning system. However, implementing switches into the steering wheel of a vehicle require a high operation force in order to prevent unintentional operation while driving, necessitating a need for a more define clicking sensation in such switching components. Based on this need, Alps Electric has developed new SKPR Series TACT Switch for automobiles, providing a more definite clicking sensation, due to its operating force of five newtons, plus an operating life of 100,000 cycles, capable of withstanding frequent usage over a long period of time.
This was achieved through company’s compact rubber spring design resulting in a silent, smooth and comfortable operation. Furthermore, the new SKPR Series employ silver contact points helping to limit contact resistance to 100m ohm, resulting in a simple development of circuit design for vehicle mounted devices operated by this product. The new SKPR comes in a small form factor, measuring only 7.5 mm in width, 7.8 mm in depth and 6.5 mm in height. All these features have been achieved through company’s proprietary thin-wall molding engineering, ultra high precision press process engineering as well as automatic assembly engineering. The company is planning the sample shipment from March 2010.
