4 way light switch with power feed via the light
This circuit diagram shows wiring for a 4 way circuit with the power source at the light fixture and the switches following.
A two-wire cable (C2) is run from the light to the first switch (SW1) and a 3-wire cable runs between all the switches. The hot source is connected to the common terminal on the first switch (SW1) and the hot terminal on the light fixture is spliced through all the light fixture to the common terminal of the last switch (SW3).
The travelers run from the first switch (SW1) to one set of terminals on the 4 way (SW2) and from the second set to the travelers on the last 3 way (SW3). The hot to the light is from the common terminal of SW3 (spliced through each switch box).

How to wire a 4 way light switch with power feed via the light switch
In this 4 way light circuit the power source is via the first switch (SW1). The hot connects to the common on that switch and the neutral is spliced through all the switch boxes to the neutral terminal of the light. A Three-wire cable runs between all the switches connecting the travelers.
A two-wire cable (C4) connects the last switch (SW3) to the light fixture, the common on that switch connects to the hot terminal on the light.

2 way light switch with power feed via switch (two lights)
The power source enters the switch box (SB1) where the neutral is spliced through to the light fixture (F1) where it is spliced to the light (LT1) and, via cable C3, to the second light LT2. The hot from the power source connects to the 2-way switch (SW1) where it can be switched to the hot terminal of the light LT1 and spliced through to LT2 via the cable C3.

Two lights between 3 way switches (power via a switch)
Shown below are two fixtures between 3 way switches.
The power source is via the switch box SB1 and a 3-wire cable (C1) runs from there to the first fixture (F1). Two, 2-wire cables (C3 and C4) run between the fixtures, and a 3-wire cable (C2) runs from the second fixture (F2) to the second 3 way switch (SW2).
The hot source is connected to the common terminal of SW1. The neutral is spliced to the white wire feeding the first fixture, via cable C1,where it is spliced to the neutral of both lights. The traveler wires from the two switches pass straight through the fixtures via cable C3.

3 way light switch with power feed via the switch (two lights)
Here we have multiple lights controlled by 3 way switches.
The hot from the power source (cable C1) connects to the common terminal of the first 3-way switch (SW1) and the neutral is spiced, in the switch box SB1, through to the second 3-way switch (SW2) via the 3 wire cable (cable C2, that also carries the travelers that connect the two switches) where it is spliced through to the first fixture (F1) and connects with the neutral of each light. In the same way, the hot from the common terminal of the 3-way switch SW2 connects to the hot terminal on each light via cable C3 (spliced in fixture F1).

3 way light switch with power feed via the light (two lights)
The power, cable C1, joins the circuit at the light fixture F1. Here the neutral connects to the light F1 and is spliced through to light F2. The hot from the power source is spliced through both fixtures and terminates at the common terminal of SW1 via cable C3.
The travelers of each switch are connect together using cable C4 (taped white and red wires).
The taped white wire of cable C3 is the hot to the light LT2 (where the red wire of cable C2 is used to splice the hot to the next light, LT1).

Three way light switch with power feed via the light
In this light switch wiring diagram the power feed joins the circuit via the light fixture where a two wire cable (C2) runs from the light, to the first 3-way switch (SW1), and a 3 wire cable (C3) joins the two switches. The hot source is spliced to the white wire (which should be marked as being hot with black tap) and run through to the common terminal of SW1, and from here the hot from the light is spliced through to the common terminal of the second 3-way switch (SW2).

3-way light switch with power feed via the light switch
Here we have a single light controlled by 3 way switches.
The hot from the power source connects to the common terminal of the first 3-way switch (SW1) and the neutral is spiced through (SB1) to the second 3-way switch (SW2) via the 3 wire cable (C2, that also carries the travelers that connect the two switches) where it is spliced through (SB2) to the neutral terminal of the light. The hot from the common terminal of the second 3-way switch (SW2) is connected to the hot terminal of the light.

2 way light switch with power feed via light
The power source enters the light fixture where the neutral connects directly to the neutral terminal of the light. The hot wire from the source is spliced through to the 2-way switch and via the switch to the hot terminal of the light.
