Cam switches
Cam switches are manual low voltage electrical switches. They are classified as layer fasteners. Their main elements are a knob and an axis with insulating plates attached, on which there are characteristic recesses for the connection program. These plates are often referred to as cams, hence the name of the hardware. The operation of this type of connectors is very simple. Turning the knob changes the position of the plate at the same time. In this way, you can switch the device on and off or switch to the desired function. Cam switches are used in main and auxiliary circuits. They perform the function of phase disconnectors or motor switches controlling 1- and 3-phase drives. The hardware is also used to connect resistors and heating elements. Individual models may differ from each other in the supported voltage and rated current as well as in the number of poles.
