Abstract
A relay circuit board includes a first external circuit structure, a second external circuit structure, an internal circuit structure, a magnetic induction element, and a switch assembly. The internal circuit structure is disposed between the first external circuit structure and the second external circuit structure. The switch assembly is disposed in a first cavity of the first external circuit structure. The magnetic induction element is disposed in a second cavity of the internal circuit structure. The internal circuit structure includes a plurality of multiple coil circuits. The coil circuits surround the magnetic induction element and are embedded in an inner wall of the second cavity. When the coil circuits are energized, the magnetic induction element generates a magnetic field.
