Simple Line Load Switch

Yes there will be some slight differences on weather or not to pigtail a short wire that leads from the switch to the yellow caps the load and or line but your ground and neutral should always be pigtailed.

Line load switch. The terminal connections are directional on a double throw switch on the other hand because it can transfer power between different loads. This line when drawn over the output characteristic curve makes contact at a point called as operating point. If the wire is coming from the top of the switch box it is likely your load wire.

Load wire generally connected to the top half of your switch. Low resistance power load switches offer reliable overcurrent and thermal protection. They are designed for general purpose power protection or for applications such as usb hot swap and power distribution.

Line wire generally connected to the bottom half of your switch. With the first device the line is the wire running from the service panel to the device and the load is the wire running from the first device to the second device downstream on the circuit. In some cases line wires are marked with line pwr or a lightning bolt symbol.

Input voltage output voltage enable and ground. The line and load terminals are. Shown below is a block diagram of a basic load switch.

Master switch goes in the box with line load. Most basic load switches consist of four pins. Outlets receptacles switches light fixtures and other electrical devices typically are wired in multiples on a single circuit.

Install your master switch. Also on some traditional switches the line wire is connected with a black or silver screw that is a different color than any other screws on the switch. There can be many such intersecting points but the q point is selected in such a way that irrespective of ac signal swing the transistor remains in active region.
