It works on every other bit of electical kit known to man. It disconnects the wires. Click. So what is the difference between disconnecting a solar panel and a switch? None.

Fundamentally you are quite correct but practically switches are a lot more complicated - at least the good ones are; cheap ones - not so much.
Some factors that go into the design of a quality switch include: - Contact material suitable for load and type of signal
- Contact pressure
- positive "snap action" when opening to minimise arcing
- minimum (nil?) contact bounce when closing
- contacts sealed from the external atmosphere
- robust construction
- secure method of mounting
- secure method of attaching wiring to terminals
Of course there is a shipload more features to consider so while the humble switch is just another method of disconnecting wires, it sometimes is a good method
However, I'm happy to just use the connectors to disconnect a solar panel!
