The QS5 cam starter is suitable for AC three-phase asynchronous motors with a voltage of 500 volts, a capacity of up to 18.5 horsepower, and a frequency of 50-60Hz. It can be used for direct starting in forward or reverse direction, stopping in use, and switching between two circuits.   
The main body of this type of cam switch is a rubberwood seat, and all other components are installed in the rubberwood seat, resulting in a small volume and compact structure. This relationship utilizes wheels with different outer edge shapes to push the contact points to complete the opening and closing actions of the circuit, and uses pure silver material as the contact points. Ensure good electrical contact and chemical stability. For operational safety, all live parts are protected with aesthetically pleasing aluminum shells.  
The product complies with standards such as VDE0660 and GB/T14048.1.
