I have been tryin to find an actual demostration of this experiement and it seem impossible to find. can someone sow me this experiment done on a single setup. where you have a light source, two slits a screen and an ''observer''. That swithes from interference pattern to two lines, by switching the observer on and off. I am convinced that the science is solid, in its theoric and applied aspect. but that this interpretation of it is complete bullcrap. And i am annoyed by the ''believe this cheap explanation''that is repeated and nauseam. What is the actual equipment required, wave lenghts, slit sizes. I know This is science meme sub, where is the sub where i can find an actual two slit operator?

What are you trying to see exactly? There's this video done with polarizers: https://youtu.be/unCXuRXpEhs Of course, it's not an instant on/off but having an instant on/off doesn't really change anything.

https://en.m.wikipedia.org/wiki/Double-slit_experiment

Put a filter on one slit to measure the beams. Done.

Edit: this thinks about a related experiment, where you build an interferometer instead of a double slit. Now rephrase the experiment s.t. you have to beams serviced from a singular beam. interfere the two beams with each other. If you measure on one beam path (e.g. Pol filter) you destroy the interference pattern.

You don't really need an on/off switch.

By default you are not observing what slit it goes trough so you should always see the wave pattern.
