Working Principle Of Capacitive Contactors

The working principle of a capacitive contactor is based on the effect of an electric field. An electric field is formed between the two electrodes of a capacitor. When a voltage is applied to the capacitor, the amount of charge stored in the capacitor changes, causing a change in the capacitor's capacitance and the magnitude of the electric field. This voltage change generates an attractive or repulsive force, causing the contacts on the moving plate to make contact or separate from the contacts on the fixed plate.
