Vandal-proof short-travel system

9 March 2005 Switches, Relays & Keypads

Rafi's new 'vandal-proof' illuminated RG 85 III input system has been designed for severe conditions of use. It is ideally suited, for example, for key panels in elevators or on public terminals. Protection against vandalism is achieved by the special design of the component housings and the flush metal surface.

The RG 85 III system has a modular design and the individual elements are fastened to a U-rail on the back of the front panel with two quick fasteners. The elements are connected using an 8-wire flat-ribbon cable with a keyed Micro-Match socket connector. Actuators and indicators are available in either round or square design in the form of buttons, keylock switches and signal indicators. A special feature of this system is the illumination of the keyswitches: The key edge and the actuating area can be illuminated in different colours.

The Rafi RF 19 short-travel keyswitch is used as the contact element. It provides a distinct tactile feedback and is available as a normally-open type or 1 NC + 1 NO type with either gold or silver contacts. Accordingly, it is rated for currents of up to 50 V, 250 mA.
