Mechanical switches are pretty easy to understand—the contacts touch, the current flows, and Bob is, presumably, your uncle. But what about soft switches? Well, they’re not that difficult to ...

The circuit was constructed to produce a frequency divider with the use of flip flops which are the basic building blocks of sequential logic circuits while forming a T flip-flop configuration. Toggle ...

Toggle, slide, push-pull, push-push, tactile, rotary, etc. The list of available switch styles goes on and on (and off?). Naturally, as mechanical complexity goes up, so (generally) does price. Hence ...
