SMARTFLOW® Global Thinswitch® Limit Switch

Liquid Resistant Limit Switch 3mm/4mm Height

The SMARTFLOW® Global Thinswitch Limit Switch helps prevent accidental mold close in injection molds by verifying ejector plate return in injection molds with 3mm or 4mm rest buttons, and where occasional water or oil spray is present. A polyurethane dome covers the actuator spring, protecting internal gold switch contacts from environmental contamination.

A special mounting bracket aids installation from the edge of the mold. The bracket allows molders to slide the Thinswitch into place without disassembling the mold or using screws to hold the switch in place.


  • Over 14 million cycle life
  • 176F (80C) standard temperature rating
  • Adjustable actuation between 3.2mm and 4mm from the switch base (excludes spacer)
  • 3mm thick design fits snugly behind the ejector plate between the rest buttons
  • Stripped and tinned 2m wire leads
  • Mounting screws and wire clips included
  • Special mounting bracket allows slide-in switch removal; protects cable from damage between mold changes
