ALPS Introduces “SKTC Series” Double-Action TACT Switch

The Industry’s Smallest Double-Action Type

Munich, Germany, June 02, 2014 – ALPS ELECTRIC EUROPE GmbH has developed and added to its product lineup the “SKTC Series” Double-Action TACT Switch™ (IP67-rated), ideal for embedding in smartphones and other mobile devices. Smartphones and other mobile devices are becoming increasingly portable and sophisticated, requiring the electronic components inside them to be ever more compact while retaining their functionality. Reducing the size of a switch or other control device, on the other hand, can sometimes have an adverse effect on operating feel and operability. It is a particularly difficult challenge technically to both reduce the size and retain the functionality of mobile device components like camera shutter buttons, which require a two-step press function for focusing and capture. Recognizing the needs of the market, ALPS has developed the SKTC Series Double-Action TACT Switch™, the industry’s smallest. By adding the SKTC Series to its product lineup, ALPS is responding to diversifying market requirements. The SKTC Series boasts the industry’s smallest dimensions for a double-action type of 3.40 × 2.20 × 0.62mm, achieved using mechanical engineering technology built up by ALPS over the years. In addition, a new metal contact was developed to generate an operating feel. By optimizing the shape and material of the contact using proprietary know-how, ALPS managed to both reduce size and realize an excellent feel. To ensure reliable operation, a projection structure was adopted for the metal contact. This increases the size of the area for operating the switch, widening the mounting accuracy tolerance range. At the same time, it removes the need for projections into the switch button, thus facilitating integration into end products. In addition, the projection structure used is an “inner projection.” This increases projection strength, thereby improving durability. Features The industry’s smallest double-action TACT Switch™ 1.
