Here two 4 way and two 3 way switches are used to control lights from four different locations. The source is at SW1 and the hot wire is connected to the common terminal. Three-wire cable runs between all switches and 2-wire cable runs from the last switch to the light fixture. The light hot connects to the common terminal on SW2.
The two 4-ways are located between the two 3-ways and the traveler wires run from SW1 to T1 on the first 4-way. T2 from that switch is wired to T1 on the second 4way and the output from there to the traveler terminals on SW2.
If your switches stop working they may be worn out or the screws may have come loose. If you’ve wired a new switch correctly and the circuit still doesn’t work, the switch may be defective. Check that all connections are tight. Check the switch, remove it from the circuit and test for failure with a continuity tester or multimeter set on the Ohms setting.
The source in this circuit is at the first switch and the light fixture is located between SW1 and SW2. Three-wire cable runs between each switch and the light fixture. The hot source wire is connected to the common terminal on SW1. The common terminal on SW2 is connected to the hot terminal on the light. The traveler wires are spliced at the fixture box to run between the traveler terminals on the switches.
