Abstract: An overload protection switch includes a main body and a press button. Several terminals, a conductive plate and other components are arranged in the main body. By means of switching the press button, the switch is switchable between an on state and an off state. In case of overload, the conductive plate will separate from one of the terminals to switch off the switch. The components arranged in the main body will not hinder the conductive plate from separating from the terminal. When switching on the switch, the conductive plate resiliently contacts the terminal. In case of overload, the conductive plate separates from the terminal to switch off the switch so as to provide overload protection effect.

Abstract: An override protection circuit device including an operation unit, a rectifying/stabilizing unit, a load voltage sampling unit, a relay and an auto-detecting/activating unit. The operation unit includes a comparator and a standard comparison voltage. The load voltage sampling unit has a voltage-dividing sampling section for obtaining a load sampling voltage from the circuit and outputting the load sampling voltage to the comparator. The comparator compares the load sampling voltage with the standard comparison voltage so as to judge whether the load power exceeds the nominal value. In the case that the load sampling voltage is smaller than the standard comparison voltage, the comparator works normally and the relay is kept switched on. In the case that the load sampling voltage is higher than the standard comparison voltage, the comparator is in an override state to switch off the relay.

Abstract: A circuit device of an override protection switch, including an operation unit, a rectifying/stabilizing unit, a load voltage sampling unit and a relay. The operation unit includes a comparator and a standard comparison voltage connected to the comparator. The rectifying/stabilizing unit serves to provide DC voltage for the circuit. The load voltage sampling unit has a voltage-dividing sampling section for obtaining a load sampling voltage and outputting the load sampling voltage to the comparator for the comparator to compare the load sampling voltage with the standard comparison voltage. In normal state, the relay keeps the circuit closed. The signal output terminal of the comparator is connected to the relay. With the bulb as the load, in the case that the bulb within the nominal wattage range is used and the load sampling voltage is smaller than the standard comparison voltage, the relay keeps closed to switch on the circuit.
