You could replace it with a cheaper single-pole switch and reuse the 3-way switch elsewhere. In alternative designs, low-voltage relay or electronic controls can switch electrical loads, sometimes without the extra power wires. When this 3-way configuration is working properly, the remaining mechanical switch is not being used as a 3-way switch. Double pole, double throw (DPDT) switches allow control from three or more locations. If a Neutral wire is not present on the line side, the KS230 cannot be. If the pilot light is in the 3-way switch at the LOAD end, then only 3-wire (two travelers and a neutral) is required between the two switches. This wiring diagram shows both buttons aligned with the fixture at the end. A wiring diagram that I received by email from Leviton (attached) confirms it. A very common type of 3-way electrical diagram is when the power supply wire moves from one switch to the second switch and finally terminates at the fixture. The KS230 does require a Neutral wire to be present at the Line side of the 3-way run. Turns out that the wiring diagram (attached) from Pass & Seymour Legrand is just simply DEAD WRONG.The possible wires are the Ground and Neutral. The 3 mandatory wires are the 2 traveler wires and the line/load wire. The two hot wires of three-wire cable connect to a pair of brass-colored traveler terminals on each switch. A 3-way switch will have 3 mandatory wires and 2 possible wires. In this diagram, the incoming hot wire attaches to the first switch's common dark-colored terminal. When the load is controlled from only two points, single-pole, double-throw (SPDT) switches are used. This 3 way switch wiring diagram shows how to wire the switches and the light when the power is coming to the light switch. In contrast to a simple light switch, a single-pole, single-throw (SPST) switch, multiway switching uses buttons with one or more additional contacts, and two or more wires are run between the switches. A common application is in lighting, where it allows the control of lamps from multiple locations, for example, in a hallway, stairwell, or large room. In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location. You can use tools or colors to label the different types of wires used and use different line styles to show charged or uncharged wires. Light switch at one end, lights in the middle, light switch at the other end. This may be one of the most common way to wire a 3 way switch. A very common type of 3-way electrical diagram is when the power supply wire moves from one switch to the second switch and finally terminates at the fixture. Option 3: Power to switch - to light - to switch.
