The following"slack cable" style switch has 1 NO and 1 NC"Slow-Make" contacts for use in normal start-stop applications. This switch does NOT latch in any position and should only be used for non-emergency applications.
The action of this switch is that when the switch actuating arm is pulled by a cable the switch contacts will change state, the NO will close and the NC will
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 and the contacts return 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 powder coat painted white.
Each captive terminal on the replaceable contact block will accept (2) #14 AWG stranded wires.
There are two 1/2" NPT conduit openings. The maximum cable recommended cable length is 200 feet with a maximum interval support of 10 feet.
The mechanical life of the switch is in excess of 150,000 mechanical and 1,000,000 electrical operations.
This type of device can be found on various conveyor installations as well as other stations that require the"pull-on","pull-off" function.
The rugged construction and long term reliability makes this cable pull switch well suited to function within various environments.
