The Smallest Part in the Panel Does the Most Work This tiny component controls machines you rely on every day: It is called a contactor. Inside HVAC systems, compressors, lighting panels and industrial equipment, a contactor is what allows low voltage to safely control high power circuits. Small control signal → energizes the coil → closes the contacts → power flows. That is how: * Air conditioners start * Motors turn on * Fans spin * Lighting systems activate Most people never see a contactor.
