In general, circuit breakers are overloaded? M, @ An overcurrent detection device that attracts the armature during live operation and a tripping mechanism are integrated into an insulating case, allowing the electrical circuit in a normal state to be opened and closed by manual operation, and to prevent overloads and short circuits. When an overcurrent occurs, a tripping mechanism is activated in response to the overcurrent detection device to automatically cut off the electrical circuit, but with conventional circuit breakers, the electrical circuit is opened and closed by manual operation. Because the operating knob for the switch protrudes from the case and performs oscillating displacement movement, if it is mounted on a panel, etc., when operating other operating switches in the panel, the operating knob may be touched by mistake, causing damage to the circuit. Occasionally, the circuit breaker would flip open or close.

As explained above, the present invention has an operating knob that slides and displaces, unlike the conventional operating knob that protrudes from the case and performs rocking displacement. When installed in the panel area, there is no chance of accidentally touching the circuit breaker's operating knob when operating other operating switches in the panel and unintentionally flipping the circuit breaker. It increases safety and has a better appearance than conventional products because it moves parallel to one side of the case.
