The simplest kind of switch is ON-OFF. This has two terminals, and simply interrupts the electrical path. Such a switch is referred to an SPST, or "single-pole single-throw", because it switches one circuit or "pole" in one way, or "throw". More complex switches are simply combinations of this basic element.
