Pushbutton switches utilizing Hall Effect technology employ a magnetic field to detect the actuation of the switch. Hall Effect sensors measure changes in magnetic fields and convert them into electrical signals. In pushbutton switches, a magnet inside the switch interacts with the Hall Effect sensor to register button presses. These switches offer advantages like durability, long lifespan, and resistance to environmental factors such as dust and moisture. They find applications in automotive controls, industrial equipment, and consumer electronics where reliability and consistent performance are paramount.
