Problem with the "Unistop" Inca bandsaw contactor

[meta_z]

Hello,
I bought a second-hand Inca bandsaw model 342.186 from 1982. The problem is that the button does not stay in the "on" position, it returns to the initial position.
Do you know what I could replace it with?

I add what there is to mark on the plate, because you can't see everything very well in the photo:
Type: LS80P
No: 208712
Year: 82
kW: 0.45
hp: 0.60
Hz: 50
Tr|mm: 1000
pH: 1
IsoltCl: 8 (or B?)
Room °C: 40
Serving: S3 40
Protection: IP54
V: 220
A: 4.8
Capacity: 16
on the gooseneck, on some models there was the possibility of adding a double push button. Do you know if it will be possible to do this?
I could redo this notch on the door to embed a double push button but how to connect it to the contactor?

Being French, I tried to find a solution in France but could not find a solution or someone passionate about Inca saws. if anyone knows his saws and can help me because I'm afraid I'll never be able to use them

You could contact Inca | Woodworking Machinery & Accessories
They are in France and have various spares - I think the main contact is Mike - very helpful.
I haven’t looked too closely, but just possibly this is the part you need INCA 53.186.031 Switch for Euro 260, 220-240v 1980 -1990 model

Salut

Well I solved my problem, an electrician friend helped me and took the coil apart. A plastic part was broken. So I modeled the part in 3D and I improved the part compared to the original one to improve its resistance, then printed and glued. He also explained to me how the contactor works and suddenly my machine finally works!!!!!
