Abstract

The present invention relates to a circuit control protection device, which is operable by depressing a switch to drive simultaneous movement of a control link set for pulling or pushing a contact plate to bounce and thus switching a circuit between an ON state and an OFF state. The present invention is characterized in that the switch is coupled to a control link set, which comprises a pull link and a push link between which a contact plate is movably arranged. In operation, the switch drives the control link set, so that the pull link of the control link set pulls the contact plate or the push link of the control link set pushes the contact plate to make the contact plate bounce to set OFF state or ON state of the circuit. When the switch is in the ON position, the push link is rotated a predetermined angle so that a bouncing space DeltaS is formed between the push link and the contact plate. The bouncing space DeltaS provides the contact plate with a free space for displacing toward the push link and thus effecting disengagement. In case of over-current, the contact plate is subject to heating and deformation so as to bounce in opposite direction and is no longer constrained by the push link of the control link set. The contact plate is thus deformed and thus effectively effecting disengagement to set the circuit to a complete OFF state and ensure operation safety.

V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) [Technical Field to Be Invented by the Invention] The present invention relates to a circuit control protector (6) which is a combination of a control lever member and a state of being energized (〇N). Controlling the displacement of the push rod of the t group, so that an AS is formed between the end of the push rod and the contact piece. When the current is overloaded, the bounce space AS provides a path for the contact piece and the reverse double bounce, and the contact piece can be smoothly Jump, the complete power down (0FF) state of the loop. Take the road [prior art]

The operation of the power control switch mainly consists of performing two current strokes of energizing the current loop (jN) and powering off (0FF). In addition to performing both power-on (ON) and power-off (〇Ff) functions, many current switch structures also have the function of automatically tripping and power-off when current overload and overheating, avoiding fuses or breakers of current loops during current overload. There is no immediate risk of power outage or tripping. The patent application case of the I power control switch is invincible, such as Shen Ren himself Φ 月月# T Mingguoguo patent No. 5, 262, 74 8, other US patent brothers 4,1 67,720, 4,937,548 , 5,223,8 1 3,
