Abstract

The present invention relates to a circuit control protector which actuates a control rod piece synchronously by pushing a button to swing to push and pull a contact piece to bounce so as to make a circuit form an ON or an OFF state. The circuit control protector is characterized in that the control rod piece is assembled on the button, the control rod piece is provided with a clamping slot, and the clamping slot movably holds a contact piece. When the circuit control protector acts, the button links the control rod piece to make the clamping slot of the control rod piece pull or push the contact piece to make the contact piece bounce and bend to both sides to form the ON or the OFF state of a circuit. When the button is in the ON position, a first side edge of the clamping slot of the control rod piece is disengaged from the holding of the contact piece. When the current is overloaded, the contact piece is deformed by heating, and bounces to the direction of the first side edge without the limitation of the clamping slot of the control rod piece, and the contact piece can freely deform and easily bounce to form the complete OFF state of the circuit and ensure electricity usage safety.
