Relay - Wikipedia

A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.

Guide for Relay Module with Arduino | Random Nerd Tutorials

A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. Controlling a relay module with the Arduino is as simple as controlling any other output as we’ll see later on.

Raspberry Pi: Control Relay switch via GPIO

O ften you want to control modules with a higher voltage with the Raspberry Pi. For this purpose, relays can be used on the Raspberry Pi: The relay “switch” is utilized by means of a low-voltage pulse. Since the Pi only tolerates a maximum of 5V (the GPIOs even only 3.3V) without relays, there is the risk that the Pi could burn out.

power supply - DC Relay Module for Switching ~200 VDC @ 1 ...

My initial approach was to switch the power using a 30 VDC 10A optocoupler relay module. I understand that this will certainly cause arcing during switching if the line is hot. However, I can cut off the mains input to the power supply right before the switch, and prevent any arcing since the relay would switch on a cold line. I'm sure that would work for mechanical switches, but is my ...
