Abstract

This invention discloses a circuit control protector (II) with a control rod operated synchronously with the movement of a press button to push or pull a contact by pressing the press button to define an electrically ON or OFF state of the circuit. The invention is characterized in that an end of the press button embedded into an end of a link, and a clamping slot at another end of the link rod is movably clamped with a contact, and a lateral side of the link rod is pressed at an oblique surface of a protrusion. During operation, the press button is moved to drive the link rod to move up and down or left and right. If the press button is situated at ON position, the link rod will move transversally to a side of the clamping slot to separate the contact, such that the contact will jump off freely towards a side of the clamping slot. For an overloaded current while the current is at ON state, the contact will be heated and bounced in an opposite direction. The link rod will not be clamped by the clamping slot anymore, and the contact plate will be jumped off successfully to form a totally OFF state of the circuit, so as to protect the safety of using an electric power.

[Technical Field to Which the Invention Is Applicable] The present invention relates to 'Chi & circuit control protection crying (-), the side of the tilting lever member elastically abuts against a convex one, and when the system is tilted, When the ":::: is pressed between the linkage lever and the contact piece, when the circuit is in the ON position, the linkage lever is provided with the button: the edge = the state of the contact contact piece... 吏 the contact piece 2: Two free trips · 'In the circuit conduction (10)) state, current over = slot: = can be smoothly tripped, forming the end of the circuit loop: =;), [Prior Art] The operation of the power control switch is mainly to implement the current loop Power-on (ON) and power-off (0FF) two kinds of actuation strokes. In addition to performing power-on (〇n) and power-off (OFF) functions, many current switch structures also have automatic tripping and power-off when current overload and overheating. Function 'to avoid the danger of power failure or tripping of the current circuit fuse or breaker when the current is overloaded. The patents of various conventional power control switches are numerous, such as the applicant's own US patent 5,262,748, other US Li, No. 4, 167, 720, No. 4, 937, 548, No. 5, 223, 813, No. 5, 451, 7 2, No. 5, 5, 58, 2, 1 ... are numerous, but all patents have commonality. The shortcomings are as follows: (1) There are many components linked to each other, and the stroke of the linkage is complicated, which generates a non-immediate action relationship between the button and the terminal component, and also increases the manufacturing cost.
