Switches

Switches are devices designed to allow current/voltage to pass or not to pass, depending on whether it is "open" or "closed". There are many different configurations available to satisfy many different applications. They are as simple as a single pole, single throw (wall switch), to the much more sophisticated "gauge" type switches that have multiple layers and can switch many components off or on at the same time. They come in many different packages as well. Membrane switches are common in touch pads, float switches are reed switches that are activated by magnets, and mechanical switches are sets of contacts.
