The Compro signal towers CO ST40 and CO ST70 represent the new generation of signal towers. They have been specifically developed for use in industrial applications and serve to visually indicate an operating status. The signal tower elements are available with either 2 or 4 functions. Using a dip switch, you can set either the 4 functions of continuous light, flashing light, double flashing light, and rotating light, or alternatively the 2 functions of continuous light and blinking light. The elements are available in the colors red, yellow, green, blue, and clear, as well as an acoustic element. The acoustic element has settings for continuous or pulse tone. With the help of our extensive accessories, you can customize the signal towers to suit your specific needs.
