Mains Step Switches
Mains Step Switches are used for transformer tap, heater, fan speed and welding machine selections. Step cam switches are rotary switches that select more than one output position on the same shaft. Choose the number of steps, current, phase configuration and the need for a 0 position according to the character of the load. Star-delta starting and step selection are not the same switch type.
