A two way switch has three terminals its a little more complicated (any useful) than it’s one way cousin. Here is our selection of two way switch circuit diagrams. Actually, electrical retailers don’t vend one-way type switches due to the price difference. If you look inside an existing wired in two way switch you will see quite a few wires of differing colours. Two way switch lighting circuit diagrams. To switch from two locations you'll need 2 two way switches and wire them together in a particular way. However if you need two switches to control a single lighting circuit, such as in the case of at the head and foot of stairs so you can switch the lights on and off in both places, you need to understand a 2 ‘way’ switch. Two way switches are frequently used on a stair case, large space with switches by every doorway. Here is a standard wiring symbol legend showing a detailed documentation of common symbols that are used in wiring diagrams, home wiring plans, and electrical wiring blueprints. Fig 3: Two way light switch mechanism Each of the gangs (or switches) above in Fig 2 (of which there are three) work like this (Fig 3): In position 1 (when the switch is down or ‘on’), COM and L1 are connected together (just like the one way switch ).
