Knitter-Switch has announced its CTK series of capacitive switches, which are an alternative to the popular anti-vandal pushbuttons, according to the company. The switches have a mechanical resistance rating of IK10 and a dust and water rating of IP68. Due to their integrated electronic system, they can be used with a latching function and NO, NC or changeover contact. The use of ring illumination, legend etching or an indicator light with one or two LEDs are also 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. They can be ordered in 22mm and 16mm versions.
