Capacitive switches: vandal-resistant and smart
The capacitive switches from knitter-switch, series CTK, are an alternative to the popular anti-vandal pushbuttons: Their IK-rating (mechanical resistance of the visible parts) of IK10 is conform to highest requirement categories. And also the IP rating for dust and water is IP68. But they are smarter than the normal vandal resistant types: Because of integrated electronic they can be used with momentary and latching function and NO, NC 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 for front panels which have been designed for vandal resistant switches. In addition to that they can be ordered in a 22 mm and a 16 mm version. Caused by the electronic inside the switches work in a voltage range from 5…30 VDC. There are two models of contact rating: 0,2 A and 1,5 A. With this it is even possible to switch high-power LED –lamps.
The capacitive switches – as well as the complete wide range of standard DIL, tact, rotary encoder, toggle and push-button switches are available directly from knitter-switch and a number of distributors throughout Europe. Samples are available on request.
