| The switches are "slack cable" style with "slow-make"-"slow-break" contacts. The switches are not "positive break" or "positive transfer." These devices should not be used for any emergency stop application. The function of these switches is such that a device that is listed as NO uses an NC contact block which is held open by a spring in the switch body. Pulling of the ring eye collapses that spring, allowing the contact block to close and actuate the circuit it is connected to. Releasing of the rope then allows the spring to expand thereby opening the contacts. The reverse is true for an NC listed switch. The contact cavity of the switch has a provision for the addition of one more contact block. Each captive terminal on the replaceable contact block will accept (2)#14 AWG stranded wires and the contacts are gold plated to eliminate high resistance tarnishing. The life of the switches is in excess of 1,000,000 mechanical operations. The momentary version of this light to medium duty switch can most often be found being used with a rope hanging down for control of an overhead door. The maintained style requires that resetting take place at the switch so access must be considered when installing it. The housing and cover are molded from high impact glass filled poly carbonate plastic. The NEMA/UL/IP classification (rain tight) allows the switches to be used outside. The maximum recommended rope length is 33 feet with the maximum interval support of 10 feet. | |||||||
