SMARTFLOW® Global THINSWITCH® Limit Switch

Liquid-Resistant Limit Switch – 3mm/4mm/.188″ Height

Global Thinswitch Limit Switch helps prevent accidental mold close in injection molds by verifying ejector plate return in injection molds with 3mm, 4mm or 3/16″ 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.
