LED backlit capacitive switch module

August 06, 2014 // By Graham Prophet
HMI Solutions providers Stadium IGT, are offering OEM control panel designers a route to design-in LED backlit capacitive switch modules in component form – a technology usually only available as part of a custom design package.

The switches feature Stadium IGT's method of combining the benefits of capacitive switching with multi-colour area-specific backlighting. Available in 20 mm and 35 mm diameter versions the capacitive switch modules are suitable for mounting into panel thicknesses of up to 7 mm and 11 mm respectively. The full RGB LED illumination provides a high-brightness user touch area with uniformity of Illumination. The solid state switch design has a non-latching output of 40 mA maximum operating from a supply voltage of 6 VDC to 28 VDC. The 35 mm version offers designers adjustable low, medium and high touch sensitivity to suit the application. The operating temperature range of the switch modules is 0° to 50°C

Terry Moss, Sales and Marketing Director of Stadium IGT, comments, “Our thin-film LED backlighting is a major selling point for our custom designed capacitive switch based control panels. We recognise that for smaller projects a custom panel may not be appropriate and therefore have developed these stand-alone products. Off the shelf standard backlit switching solutions also offer panel designers a means to prototype and evaluate HMI designs without the need to develop custom capacitive sensors and backlighting.”
