A voltage and current protector switch is a safety device designed to protect your electrical appliances from dangerous power surges and irregular currents. It safeguards your devices by detecting and limiting both over-voltage and over-current conditions. By either blocking or diverting excess energy to the ground, it ensures that only safe levels of electricity flow through — helping to prevent damage, extend appliance lifespan, and enhance overall electrical safety in your home or office.
