Abstract

Printed circuit boards and breadboard devices have contact pads and magnetic component connectors where connection between the contact pads and the magnetic component connectors are made by magnetic force. Either the contact pad or the magnetic component connector will be magnetic and the other will be made of a material to which a magnet will be attracted. For example, printed circuit boards, which usually have copper traces, include contact pads made of a material to which a magnet will be attracted. Circuit components are connected to magnetic component connectors having magnetic legs which then connect the components to the contact pads of the circuit board or breadboard device. This makes the connection of components to a printed circuit board or breadboard device fast and easy and provides for easy removal and replacement of components. Magnetic component connectors can also be configured to connect magnetically to one another.
