Buttons are always equipped with a normally open and normally closed contact. The different colors of the buttons (6 colors) are based on DIN60204-1 (color coding of control elements and their meaning). The buttons are suitable for passing on pulse control commands in almost any
electrical system. They can also be used to operate light groups using pulse commands, e.g. to a step switch, directly on site from the sub-distribution board or distribution cabinet. The module width is always 9 mm (0.5 HP).
