Alps Eleletric Europe has developed the SSCQ Series compact detector switch with two-position output in two directions for use in zoom lever control of mobile devices such as compact digital cameras and digital camcorders. Mass production commenced in February 2012. Two detection positions in each direction, or four positions in total, allows control over zoom speed depending on how far the zoom lever is moved.
The switch lever is longer than levers of earlier switches and is taller than the main body of the switch. This design makes the switch lever easier for the protrusion on the device’s zoom lever to catch. The result is greater freedom in device zoom lever design.
A single circuit with four contacts (two detection positions on each side) supports greater functionality of devices. Principal applications are control of high-power zoom for digital cameras and other mobile devices.
