JET pneumatic switches have been designed to meet the ever increasing need to save space without compromising on performance or reliability. Available in two port options, M5 threaded, or quick couplings for assembly purposes. The limit-switches, mounted on sub-bases with threaded connections or with quick couplings, may be combined with different types of manual operators for panel mounting complying with the various needs of the plant. It can also be used as an operator on indirectly operated 3 and 5-port valves where a sensitive control is required.
