Contacts are mechanically opened and closed for current switching. The dog is used for operating the actuator of the Switch. The contacts perform electrical. A limit switch box is the feedback device that closes the loop between your motorized valve and your control system. After each attempt, contact opening is checked by an impulse voltage test. The purpose of this guide is to reinforce the basic aspects of ABB's mechanical limit switch offering. Readers who are. Switches: The alternating current switches and switch-disconnectors for their switching function, with load making and breaking current ratings. Contactors: Contactors are used to switch o and to switch on loads requiring these operations during normal use, especially as used in a particular. Thanks to the limit switch for electrical enclosures we get a perfect control cabinet lighting and energy savings by preventing any expenses incurred by the forgetting of light off. Our team of engineers and consultants is at your disposal to analyze your project in depth and propose the most.
