Sealed limit switch

 

Double-circuit type of limit switch, is widely used
With strong aluminum cast outer shell
High mechanical strength
Water-proof, oil-proof construction
Structure preventing oil, water and pressure
Indicating plate with setting position is installed in it, so it is easy to maintain
Various of actuators is taken convenience for using
Built-in contact stand has double-spring, so it has long mechanical life
