Rotary-Type Position Detection Switch
November 2005

 Email this Article

The company said its miniaturized SREF series is the industry’s first hinge-mounted position detection switch for miniature mobile devices. Mounted within the hinge, this device detects the position of the cover of a folding device. The switches are rotary-type position detection switches built into device cover hinges, and they directly detect cover position angles. Movement of the hinge simultaneously moves the detector’s traveling contact, which, at a preset angle, makes contact with the fixed contact. The development of this series makes possible the design of products that incorporate various compact mechanisms. A new miniature traveling contact was also developed using the company’s proprietary micro fabrication technology.
