Normal push buttons are always equipped with a normally open and a normally closed contact. The various colors of the buttons (6 colors) are based on DIN 60204-1 (Color coding of control elements and their significance). These push button devices are suitable for transmitting pulse control commands in almost any electrical system. They can also be used to control lighting groups via pulse commands, for example, at a step switch, directly on-site from the sub-distribution or distribution cabinet. The module width is always 9 mm (0.5 TE).
