Introduction
Rotary geared type limit switches are used on the control circuit of reversing drives so as to limit their rotation/movement with pre-determined position. The function of limit switch is to stop the mechanism at different combinations with totally enclosed in IP-55 degree of protection with N.O. and N.C. contracts combination. Gear ration available are 48:1 and 60:1 Application: Rotary geared type limit switches are suitable for use reversing drives such as hoists, winches, rolling mills and various other mechanisms used such used in steel plants such as coke oven, feeding machinery etc. Construction: Rotary geared type switch is basically consists of heavy duty worm gear drive. The worm gear unit is built in a cast housing fitted on main bossy of limit switch, the cam shaft which extends from behind the gear into housing, accommodation the cams adjustable actuators which are fitted on the cams. These actuators strikes the contact finger of respective contacts .................................................................................................................................................................................................................................

Application: The new range of limit switches FG has been designed and manufactured according to safety standard are suitable for use on reversing drives such as hoists, cranes, winches and rolling mills etc. Design: The driving motion is transmitted by worm gear. All gears and hubs are made of low wear thermoplastic. The rotational movements are transmitted to switches by adjustable cams. Driving cams: Each lever has a single micrometric resister screw.This screw exclusively works on its own combined lever, excluding any mechanical contact with any other nextto it. The regulation is easily made by use of screwdriver on a register screw. The special friction system assures a rapid and precise adjustment.
