How to wire a three way switch
We’ve uploaded new diagrams for three way switching (sometimes referred to as two way switching plus intermediate). so if you plan on doing some house wiring you’ll find Full instructions, schematic diagrams and installation illustrations:
These light circuit diagrams will be of use if you have 3 light switches that control a single light.

The intermediate light switch is used where three or more switches control one light and used in conjunction with two two way light switches to achieve this

There are four terminals, usually L1, L1 and L2, L2. In one position, L1 and L2 are connected in pairs. In the other position, alternate pairs are connected.

The intermediate light switch is used where three or more switches control one light and used in conjunction with two two way light switches to achieve this. It is effectively two single gang intermediate switches on one face plate.

Each of the gangs (or switches) above in Fig 2 (of which there are two) work like this (Fig 3): There are four terminals, usually L1, L1 and L2, L2. In one position, L1 and L2 are connected in pairs. In the other position, alternate pairs are connected.
