The ammeter selector switch is an important component in any electrical system that needs to measure current flow. It allows you to switch between multiple ammeters and measure the current flow in different parts of the system. In this article, we will cover the wiring diagram for the ammeter selector switch and provide some frequently asked questions about its use.
What is an Ammeter Selector Switch?
An ammeter selector switch is a device that allows you to measure the current flow in different parts of an electrical system. It works by switching between multiple ammeters, each of which is placed in series with a particular circuit or section of the overall system.
For example, a typical ammeter selector switch might have three positions: “Main,” “Generator,” and “Battery.” In the “Main” position, the ammeter measures the current flow between the battery and the rest of the system. In the “Generator” position, the ammeter measures the output current of the generator. And in the “Battery” position, the ammeter measures the current flow to and from the battery.
Wiring Diagram for Ammeter Selector Switch
Here is a wiring diagram for a typical ammeter selector switch:
| Position | Ammeter Connection | Circuit Connected |
|---|---|---|
| Main | A | Battery to System |
| Generator | B | Generator Output |
| Battery | C | Battery to Charging System |
Here are the steps to wire an ammeter selector switch:
- Connect the positive terminal of the battery to the “Main” terminal of the selector switch.
- Connect the “A” terminal of the ammeter to the “Main” terminal of the selector switch.
- Connect the negative terminal of the battery to the “Battery” terminal of the selector switch.
- Connect the “C” terminal of the ammeter to the “Battery” terminal of the selector switch.
- Connect the “B” terminal of the ammeter to the “Generator” terminal of the selector switch.
- Connect the output of the generator to the “Generator” terminal of the selector switch.
Make sure that all connections are tight and secure, and that the ammeter selector switch is properly grounded.
