ALPS Develops SDKU Series Rotary-Encoder with Power Supply Switch for White Goods
Power Supply and Mode Selection Switch Function Realized in a Single Package
Duesseldorf, Germany, February 07, 2006 - With the development of the SDKU Series ALPS ELECTRIC EUROPA GmbH offers new rotary pulse encoders with built-in power switch. These devices are extremely well-suited for applications in the area of washing machines, dryers and other household appliances. The new SDKU Series combines on/off switch and mode selection function in a single package with dimensions of only 30.2mm x 32.1mm x 29.6mm (W x D x H),

Among today’s essential household consumer electronic products, methods of mode selection and power supply function tend to vary internationally. Take, for example, the washing machine: in Japan, selecting load size settings and turning the machine on and off is most commonly done through pushing a series of buttons located on the surface of the washer’s panel. In Europe, however, rather than using buttons, the use of a single dial, to not only turn the appliance’s power and on and off, but also to select washing modes according to the clothing fabric type (such as cotton, synthetic, or wool), water temperature and other various mode settings is increasing. In the past, this type of function required installation of dial function parts along with wiring leads to the power switch and the set mode options.

Recognizing these market needs, ALPS has accomplished the development of a single package that realizes two types of functioning in a rotary-type power switch with signal circuitry.

The SDKU Series was developed based on ALPS many years of accumulated insert molding technology and realizes encoder function for mode selection, as well as power switch function. Furthermore, based on ALPS’ proprietary engineering technologies, the implementation of a detent structure with a heavy rotation torque ensures an easy handling for the user. In addition, the implementation of a sliding contact-point structure realizes an excellent durability against environmental conditions and continuous use.
