When considering the RAFIX 22QR, there are many options for designers to consider. Pushbuttons: does it need to be illuminated; if so, what color? Should the pushbutton have momentary or latching contacts? Selector switches with long and short handles can also be illuminated. Keylock switches are available with various switching positions and functions. EMERGENCY STOP buttons: dupe-proof according to EN 418, thanks to the positive-action mechanical movement sequence. To prevent inadvertent actuation, a certain operating force must be exerted at the action point and also available with illuminable window, display or key-based release. Pushbuttons are also available in 40 or 60 mm mushroom diameter actuators that are illuminable.
