Limit Switch Accessories and Spare Parts Selection Guide: Technical Criteria & Application Standards
Limit Switch Accessories and Spare Parts selection guide: technical parameters, mounting and compliance standards, and Isıso, EMAS comparison.
Limit switch accessories and spare parts are complementary parts consisting of replacement contact blocks, safety actuators and protective covers for limit switches and door safety switches. They are used to repair a limit switch with a worn contact without replacing its housing, to renew the actuator fitted on the door side of a door safety switch, and to protect a miniature switch from external influences. The category includes EMAS-brand snap-action 1NC+1NO and slow-action 1NC+1NO, 2NC+1NO and 1NC+2NO replacement contact blocks, as well as Isıso T4NS series straight, 90-degree and protected 90-degree safety actuators. Select the contact block by the series of the existing switch, its contact arrangement and whether it is snap-action or slow-action, and the safety actuator by the switch model, the actuator's entry direction into the switch and the mounting location. In a snap-action contact, the speed of changing position is independent of the actuation speed, while a slow-action contact opens and closes at the speed of the actuating element. A safety actuator is not a safety switch on its own; it works only with the switch series it was designed for. The Limit Switch Accessories and Spare Parts category on Welibaba includes 12 active models from leading manufacturers such as Isıso, EMAS.
