Hameg HM303-6 K Rotary Switch reassembly and how to purchase.

Attached photo is Hameg HM303-6K.

During repairs a long time ago, the Volts/Div Rotary switches of Ch. 1 & 2 of the front panel were loosened.

I spent a lot of time trying to reassemble it, but it was impossible.

If anyone disassembles and assembles this switch, please link to a photo or video.

One had to be reassembled and the other had a broken shaft.

Please also link to where you can purchase.[/img]

Each of the 1st and 2nd springs and balls must be fully installed in order.
And it's easy to reassemble.
However, I've wasted a lot of time trying to insert it using the "?(Why)" hole.
If you use the "? (why)" hole, you can insert one, but the second is impossible.
I think this hole is the Grease injection hole.
So one was reassembled.
The remaining one rotary switch has to be purchased because the shaft is broken.
Please tell me where to buy.
