Grab Differential Limit Switch

Quick Overview

When it comes to restricting power supply Differential Limit Switch gives an optimum solution. It works on the principle of single lever grab control. They have six cam operations that work on their specific set limits. They are made for heavy duty application and are made out of cast iron exteriors. It protects the machine surface from pollutants like dirt and dust.


  • Heavy duty operation and power management
  • Six cams for enhanced control
  • Housed in IP-54 degree of protection

Other Details:

  • APPLICATION : The grab different limit switch is driven by holding and closing winches is used in auxiliary circuits for single lever grab control.It is used for stopping the closing motor after closing or opening, regardless of the height of the grab, and starting the holding motor, after closing, for transition to the hoisting action, as well as for stopping the holding and closing motors at the highest and lowest grab positions.
  • CONSTRUCTION : The switch contains six cam operated switch elements which are used as auxiliary circuit limit switches (see switching sequence diagram). The dimension drawing shows that the switch has two shafts which must be driven by the holding and closing winches.The contacts of limit switches are 40 amps rated at 500VA C.The limit switches are designed for heavy duty application housed in IP-54 degree of Protection. The housing is made of Cast Iron base & cover.The base and cover both have machined surface to protect against dirt and dust.
