These switches are slack cable style with Slow-Make contacts. The switches are not Positive Transfer and they do not latch in any position. They should NOT be used for any Emergency Stop applications. The action of these devices is that when the switch actuating arm is pulled by a cable the switch contacts will change state, that is, the NO will be closed and the NC will go open. When the force on the cable is removed from the actuator arm, spring pressure will return it to its normal position, while the contacts are held in position through a ratchet mechanism. The next time the cable is pulled, the action is repeated with the contacts returned to their original state. The housing and cover are made from a glass filled black polycarbonate. The mounting base and double end actuator arm are die cast from a high strength zinc alloy. All exterior steel components are made from #303 Stainless. Switches are provided with two 12 NPT conduit openings. The total maximum cable length recommended is 200 feet with a maximum interval support of 10 feet. The life of these devices is in excess of 150, 000 mechanical and 1, 000, 000 electrical operations. Each captive terminal on the replaceable block will accept (2) #14 AWG stranded wires and the contact are gold plated to eliminate high resistance tarnishing. These devices can be found on various conveyor installations as well as other stations that require the pull-on, pull-off function that this being provides. Their rugged construction and long term reliability make these cable switches extremely well suited to function within various industrial environments.
