Alps Unveils New Slide Switch for Mobile Devices



Low-profile, 0.7mm-High SSAJ Slide Switch is the Industry's Smallest*

TOKYO - Alps Electric announced today development of the SSAJ series, a 0.7mm-high slide switch that enables the design of more compact electronic devices including mobile phones, digital cameras and compact music players. Sample shipments will commence from February 2010.

Trends toward smaller and slimmer portable devices have led to the need for notably smaller and thinner components. Demand has been particularly strong for thin and compact slide switches, which are usually placed on the side of a device and manipulated to turn power on and off or perform a hold (pause) function. An increasing number of devices such as smartphones, many of which feature touch panel operation, have begun including slide switches to allow for easier visual confirmation of the mobile phone's pause function.

In response to these growing needs, Alps Electric has developed the industry's smallest slide switch, which, at 5.5mm wide by 2.5mm deep by 0.7mm high, boasts a 36% reduction in volume, thus decreasing the space required on a circuit board compared with the Company's conventional SSAD series (6.7mm × 3.2mm × 0.7mm) products. Moreover, this slide switch supports lead-free soldering.

Switches and other small, thin components mounted in devices that are subject to direct manual manipulation must be durable. Therefore, the operational knob on the SSAJ slide switch is reinforced by a metal plate inserted inside its plastic body.

Tactile feedback is also important to users yet because components in such small products are so tiny, it is increasingly difficult to realize proper sensation. Alps Electric leveraged its longstanding mechanical design technologies to address this issue by creating a unique structure with a plate spring, realizing a 1.5N operating force. By generating an appropriate clicking sensation, this contributes to higher product usability.

* Based on Alps' survey in terms of volume ratio as of February 1, 2010.
