How to control 3-speed fans? What is a control switch?

General questions about Sentera devices
A control switch can be used to adjust the speed of single phase 3-speed fans. Sentera 3-step control switches are available with or without OFF position. They connect the 230 VAC mains to either the start winding of the motor or to one of the connection points on the main winding of the motor. So, the 230 VAC is connected to only one of the three contacts. This allows you to adjust the fan speed from low to high in 3 steps.
