Why do remote controls resume working after you smack them?

I often thought it has something to do with the batteries of the remote but I’m not sure. And it’s applicable to most remotes too—TV, airconditioning, toys I had when I was a kid, etc.

Loose electrical connections. It could be batteries, it could be a broken solder joint, or any of a number of similar things. Smacking the device shakes all of those internals, hopefully re-establishing a broken connection in the device. Unfortunately, it also contributes to the creation of more loose electrical connections, so it’s a losing proposition in the end.
