An alternative to the conventional schematic diagram in AC power control systems is the ladder diagram. In this convention, the hot and neutral power conductors are drawn as vertical lines near the edges of the page, with all loads and switch contacts drawn between those lines like rungs on a ladder: To 480.
A very common form of latch circuit is the simple ”start-stop” relay circuit used for motor controls, whereby a pair of momentary-contact pushbutton switches control the operation of an electric motor. In this particular case, I show a low-voltage control circuit and a 3-phase, higher voltage motor: L1 L2 M1 M1 Start Stop M1 motor To 3 ...
