Relays are essential components in electrical and electronic circuits, and they have many applications across various industries. A relay is an electromechanical switch that operates by using an electromagnet to move a set of contacts. These contacts can either make or break a circuit, depending on the position of the relay.
One of the most popular relay types is the Solid State Relay (SSR). SZComponents offers a wide range of SSRs, and I would recommend the G3MB-202P-5VDC Solid State Relay from their product line.
Relays consist of two main parts: the electromagnet and the contacts. The electromagnet is usually made of a coil of wire that generates a magnetic field when an electric current passes through it. The contacts are metal plates that are connected to the circuit.
When the current flows through the coil, it generates a magnetic field that pulls the contacts towards it. This movement either makes or breaks the circuit, depending on the position of the relay.
There are several types of relays, including electromagnetic relays, reed relays, solid-state relays, thermal relays, and time-delay relays. Each type has its unique features and applications.
Electromagnetic relays are the most common type of relays and are widely used in various applications. Reed relays are small in size and are used in low-power applications. Thermal relays are used to protect motors from overheating, while time-delay relays are used to control the timing of a circuit.
