The MICON 5 series gives designers a great deal of scope. With the wide accessory range available, it is possible to design a control concept individually and to implement simple and reliable operation. The accessory range includes opaque, round and non-illuminated plungers that are the cost-effective option for system structures and feature extremely flexible height options. Another accessory is square, illuminated plungers. These excellently illuminate control surfaces are offered in various colors and are also available with corner illumination for status display. The opaque, round plungers featuring ring illumination provide a homogeneously illuminated ring area around the control panel, and finally the RK 90 keycaps are the alternatives to overlays and measure 9 x 9mm.
