Two Way Roller Lever Limit Switches are for used for EOT Cranes, Electric Hoists, Material Handling Equipment, Wagon Shunting Devices etc., to prevent over travel or traverse on power & control circuit up to 500 V.A.C. 50 cycles/second and 40 amps continuous current.  

When used as a series Two Way Lever Limit Switch the maximum permissible frequency of operation is 1000 operations per hour. When used as series Limit Switch the maximum permissible frequency of operation is 720 operations per hour. 

Two Way Roller Lever Limit Switch is remains closed and cuts off power to stop the motor of the crane. The Lever limit Switch operates when it reaches a predetermined position when the lever is moved over a projecting member / bracket fixed on the girder. The series limit switch is fitted with four sets of contacts which cuts off two phases of the motor in both direction and is suitable for 500 Volts 50 C/s AC supply system.  

The Lever limit Switch contacts are automatically reset when the lever returns to zero position due to spring action. The housing of Lever Limit Switch is made of sheet steel suitably reinforced to give exceptional rigidity. The Cam shaft is mounted in the housing on moulded bushes (bearings) to synthetic material fixed to the front and rear walls. These bearings do not require any lubrication. 

On request, the Lever Limit Switch are also made of Cast Iron / Cast Aluminium, IP-54 enclosure. The base and cover have machined surface to protect against dirt and dust. 

The Lever Limit Switch contact boxy is made of high-grade melamine suitable for heavy duty, non-tracking and is capable of withstanding heavy arcing. The contacts have a maximum current capacity of 40 amps at 500 V.A.C.

The Speed-O-Control LSR 4-way rotary limit switch with cross bar / rods operates the control change over contacts of a motor of a moving equipment. When the moving equipment operating with a load, actuates the 300mm rods of the limit switch, the NO/NC contact elements change-over to control the equipment’s movement.

The contacts operate / change-over at 90° rotations. The LSR limit switch has 4 position 0° - 90° - 180° - 270º operations used for single / two speed motor control. The LSR limit switch has 300mm rods with 3 to 4 positions and 2 or 4 contacts.
