Chainsaw Sachs Dolmar 100 off-switch

Hello dear members, I have a question about the off-switch of my Sachs Dolmar 100 chainsaw:
The switch is missing (caused by the previous owner) and I want to replace the switch for a universal one. The wire of the CDI, which is used to shortcircuit and turn off the engine is now hanging loose. Is it true that, when you use the switch, there wil be a shortcircuit and if so: Do I shortcircuit this wire with for example the carburetor?
Can someone please explain how this works and how I should connect the wire and switch?
[Sorry for my English, I'm from Holland so it may contain some mistakes 😉]

Welcome aboard! You are correct, the switch will need two terminals, one for the wire from the magneto and the other to go to ground. Just remember that OFF will be ON unless you file off the tang in the plate and turn it around.

Your last sentence is somewhat unclear to me. If I use my multimeter and put it on continuity, I can easily find out what is OFF on the universal switch. Engine OFF is when I hear a beep, so that's when I shortcircuit, am I right?
