The capacitive switches from knitter-switch’s CTK series are an alternative to the popular anti-vandal pushbuttons: their IK rating (mechanical resistance of the visible parts) of IK10 conforms to the highest requirement categories, and their IP rating for dust and water is IP68. But they are smarter than the normal vandal resistant types: thanks to integrated electronics they can be used with momentary and latching function and normally open, normally closed or changeover contact. Ring illumination, legend etching or indicator light with 1 or 2 LEDs are possible.
Based on common measurements (threaded bushing M19x1) they can be used without any change to front panels which have been designed for vandal resistant switches. In addition they can be ordered in a 22 mm and a 16 mm version. The switches work in a voltage range from 5-30 V d.c. and are available in two models with contact ratings of 0,2 A and 1,5 A. This makes it possible to switch even high-power LED lamps.
