The SSAF series of multicontrol devices combine an eight-contact slide operation–type switch with a centrally located push-switch function for small portable devices such as cell phones and handheld terminals. With the firm’s proprietary sliding contact construction, which moves the operating part in various directions, the moving contacts will either make or break a circuit with any of the eight contacts, thus determining the direction of movement of the operating part. This enables free movement of the cursor on a mobile phone display. Input instructions are read as the contacts are switched on and off, so no special integrated circuit or software is required. The firm has reportedly realized the industry’s thinnest body for a multicontrol device with multidirectional detection: 1.4 mm high without operating part and 3.0 mm with operating part.
