Good Afternoon! I have bought a new single phase motor for my Aasbrink. And I have the original drum switch that I want to use, but do anyone have a wire diagram or something similar? I found this on youtube , but I am uncertain since my motor is different connections.

Is there not a wiring schematic in the cover of that terminal box?

Although your switch looks similar to the one in the video the connections may not be the same. The first step will be to test the way the switch behaves. If there are no markings on the connections mark them with numbers or letters to identify them. Then create a table showing connectivity between the connections in all three positions. (Off, forward, reverse.). When you have done this post the results so can give you a digram of how to connect it,

Just checked and it works the same as the one in the youtube video. I have a diagram, but dont understand it. No U, V or W and what pattern, delta or star and the black and red wire must come from the capacitor? I can wire sockets, lamps and easy things, but struggle on this sort of stuff..

Remove the two metal links on the motor. (leave the wires from inside the motor on the original terminals.)

This should do what you want,


If forward and reverse are the wrong way round swap over the wires to terminals U2 and W2
