Frequently asked questions
You are correct that a relay is basically just a switch, but it's a switching operated via remote control, so to speak. A regular switch controls Electronic current by connecting or breaking the path of either the positive side of a circuit diagram.
A relay DC line is an electrically operated switch. They commonly use an electromagnet (DC Coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch the power supply ON for a circuit when the coil is activated.
Relays and fuses are two separate entities and serve different purposes. Fuses provide over-current protection. Relays allow you to control heavier loads and higher voltages with lower voltages and currents.
Relays are electrically operated switches that open and close the circuits by receiving Electronic signals from outside sources. They receive an Electronic signal and send the signal to other equipment by turning the switching on and off.
A 24 Volt thermostat circuit sends electricity to the relay coil. That coil changes the 24 Volt into magnetism. Inside the relay, that magnetism flips the switches to turn line voltage supply HVAC equipment on and off. A relay usually has multiple switching.
