The PCB relay is a safety device that is vital to any circuit board. The circuit board relay functions like a standard relay, except that it's smaller. The PCB relay has a spring that holds it in place and creates an air gap inside the magnetic circuit when the circuit is de-energized.

The PCB relay is available in a variety of options and can be custom-made to fit any specific requirement. Its compact design and robust construction make it ideal for demanding rolling stock applications. The PCB relay can provide circuit protection as well as overvoltage and overcurrent protection. It can be purchased directly from a manufacturer or from distributors online.

If you're a beginner or you'd like to increase your PCB relay design skills, you can use the Altium Designer. This software includes industry-standard circuit board layout tools and a comprehensive solution for component sourcing and management. It also provides realistic 2D views of your board. You can use it to design and manufacture relays and other electronic circuits.

PCB relays are available in both electromagnetic and reed varieties. Emitting a magnetic field when power is applied to the coil will cause the armature and contacts to move. A PCB relay can be classified based on its construction, mounting style, and function.
