Characteristics of contact module
The limit switch housing is made of die-cast aluminum, and the surface is sprayed with aluminum powder alkyd heat-resistant paint. The contact of the limit switch is disconnected by the operating arm driving the shaft to make the cam on the shaft move. The cam and the adjustment sleeve on the shaft are evenly equipped with 24 teeth on the circumference of φ26. The cam angle can be adjusted as needed to achieve the required closing procedure. When adjusting, just remove the screws on the end cover and the adjustment sleeve. The rocker arm can also be adjusted arbitrarily within 360 degrees (every 15 degrees), see Figure 1.
