5V One Channel Relay Switch
Basically, a relay is a small circuit with two outputs, one that is normally open, and the other that is normally closed. The common pin of the relay is connected to a power source and the circuit can be toggled. You can use a microcontroller to control the IN1 and IN2 signals.
The circuit of a relay switch is quite simple. It consists of three components: a signal pin (S), a voltage pin (V), and a common ground (G). The circuit works like a SPDT single pole double throw switch. In other words, a relay switches on and off when its signal pin is HIGH and is closed when it is LOW.
This simple switch works by using a high-voltage current to open its contacts. It does this by using a high-voltage coil. When a current flows through the coil, it energizes the electromagnet. This in turn moves the internal contact. The internal contact is then reset to its initial position when the current stops flowing through the coil. This is a simple but effective switch and one that can be used in a variety of applications.

A 1 Channel 5V Relay Module contains one relay. The relay can be controlled from any 5V digital output. It also features a handy LED to indicate its status. It also includes a four-pin “Grove” connector and a standard 3 pin header.
With a microcontroller development board, this microcontroller can be used as a switch to control a high-powered appliance. The microcontroller development board can handle AC and DC signals and can even control a led strip. It can also control other devices, such as a motor or a light bulb.
When choosing a relay, you need to consider several factors. First, make sure the relay meets the voltage requirements for the application. This is the maximum amount of current that can be switched between two wires in the same circuit. You should also make sure that the voltage and current of the switch are within the limits of the relay. If they are not, the switching system will be in danger of failure, and the unit under test may become damaged.
If you are switching two different circuits, then you will want to choose a relay with dual voltage capability. This is a better option because it will switch two different voltages. For example, you can switch two circuits using a 12V DC relay. These types of switches are useful for full voltage applications, since they allow a low-flow circuit to control a high-current circuit.
When choosing a relay with switch, you will also want to choose one that uses the same power supply as your vehicle. For instance, you may want a relay that alerts you when the door is opened. A relay with a switch for this purpose will have a coil fed by the headlight power cable. When the headlights are on, the relay is powered by the headlight switch, which feeds it with +12V. The door switch completes the circuit with a high current buzzer. Alternatively, you may want a relay that can also serve as a make and break switch.
