Electronics Kits Use Reed Switches
Reed switches play a crucial role in numerous electronics kits and hobby projects, serving as fundamental components for exploring various circuits and scientific principles. These versatile switches are extensively utilized in educational motor kits to illustrate the operation of brushless motors, among other applications.
In electronics kits, a reed switch is typically employed to showcase the inner workings of a brushless motor. The motor’s rotor shaft is equipped with two magnets positioned diametrically opposite each other.
Adjacent to these rotor magnets, a reed switch and an electromagnet with opposite polarity to the rotor magnets are placed in close proximity and connected in series to a power source. As one of the magnets approaches the reed switch, it triggers the switch by closing its contacts. This action energizes the electromagnet, causing it to repel the opposite magnet on the rotor, thus inducing motion. The movement disrupts the magnetic field, causing the reed switch to open again, and the process repeats cyclically, driving the motor.
In other hobby kits, reed switches are utilised to demonstrate the principles of magnetism, sensing and the extent to which magnetic fields influence their surroundings. These demonstrations help illustrate concepts such as magnetic attraction and repulsion, as well as how changes in magnetic fields can be detected and utilized in various applications.
Overall, reed switches are invaluable tools in both educational and experimental settings, providing hands-on learning opportunities for understanding electromechanical interactions and the properties of magnets. Their versatility and simplicity make them ideal for demonstrating essential concepts in physics and electronics, making complex phenomena accessible and comprehensible to learners of all ages.
