4-Way Switching Circuits If you understand the logic behind the 3-way circuit, the 4-way will not seem that difficult.
When Do You Need a 4-Way Switch? The 4-way is used when you want to control the light or lights from two or more locations. 4-Way Switch - NOT To Be Confused With a 2-Pole Switch! A 4-way switch has four terminals (do not confuse with and purchase a 2-pole switch by mistake).
The 4-way terminals are labelled “In” and “Out” (two of each). The mechanics of this switch are simple, in that they either switch the travellers straight through, or criss-cross them.
