The GO? Switch Model 72 has the smallest diameter (3/8”) of any round leverless limit switch and is used extensively in factory automation applications.

Round Series TopWorx? GO? Switches are ideal for use in harsh and hazardous, highly regulated environments where precision is key. Internal magnets are aligned to repel each other, holding the contacts in one biased position. A ferrous or magnetic target entering the sensing area attracts the primary internal magnet, overcoming the biased position of the sealed contacts, closing them, and generating a signal. With a stainless-steel construction, flexible electrical connectivity, and global and regional certifications, round GO Switches outperform inductive proximity switches in the toughest applications.
