The heavy-duty limit switch is mainly used for the position detection  of  vehicles  or  other  heavy-duty  walkinmechanisms

When the walking mechanism presses down the touch wheel,the touch wheel makes the switch to operate through the touch arm and the limit switch sends out a signal to stop the walking equipment.

The heavy-duty limit switch is suitable for working under extremely harsh industrial environment, such as driving transportation equipment in the metallurgical mine industry, stacker-reclaimer in the coal ore terminal, etc.






• Rigid cast-aluminum shell and electrostatic anti-corrosion coating, suitable for installation in harsh industrial environment

• The protection standard IP67 also to be used in harsh environment

• Excellent durability with unique design of the mechanical structure and ball bearings requiring no maintenance.

• Superior design of the internal action mechanism and high performance micro switches for stable action of the switch.
