Worm drive limit switch is used to trip motor supply when the moving loads reach the extreme end positions of working zone. Worm drive limit switches are suitable for use on reversing drives such as Hoists, winches, rolling mills and various other mechanisms used in steel plants such as coke oven, feeding machinery etc. A two (or more) contact elements are operated by respective rotating cams, suitably adjusted on a cam shaft which rotates with fixed speed ratio of the drive motor shaft. The cams can be sleeplessly positioned so that they trip motor supply and stop the motion at the set point of travel. The Rotary geared limit switches with IP-55 degree of protection are available in desired NO/NC contacts combinations and specified gear ratios.
