On-/Off-Switch

Hey!

I would also like to express my sincere gratitude for the significant effort invested in this project.

I successfully printed the case and found and installed nearly all of the components.

However, I am uncertain about the type of on/off switch to use here. I can only find suitable momentary switches on Amazon, which are not appropriate for this purpose.

The first pic shows that it actually seems to be a momentary switch. But the wiring on the second one clearly demonstrates a permanent on/off switch/ button: how can that be?

I would appreciate any assistance.
🙂
