It is metal material as preferential described fin, be simultaneously located at switch enclosure shell, on switch enclosure cover.
Embodiment 1 principle, as shown in figure 11, when this product is implemented, connects live wire on quiet contact chip, dynamic contact bar
And zero line；Press shift knob, pressing spring under the button post of shift knob, the clamp rail tooth of button post snaps in clamp rail teeth groove road, point
Declining from forks piece, movable contact spring loses separation forks piece bottom support and drops downwards, and at this simultaneously, movable contact spring briquetting is as button
The disappearance of the separation forks piece support force of post, its briquetting spring recovers elastic force under the reaction force of casing cover, the limit of pressure down of action contact frame
Position portion is driven the quiet contact site of both sides, dynamic contact site to decline by briquetting spring downward simultaneously, because of dynamic contact site itself and action contact frame
Having even hook structure, dynamic contact site now does not have too big action, and quiet contact site can by briquetting spring downward tightly
Contact is on static contact, and the movable contact of the stationary contact of static contact and the quiet contact site of movable contact spring completely attaches to, the live wire of this switch,
Zero line all can contact, and completes energising action, it is achieved " unlatching " effect of this switch；When wanting closing machine, again press
Shift knob, the clamp rail tooth of button post departs from clamp rail teeth groove road, and under button post, pressing spring recovers elastic force, lifts the linkage of separation forks piece
Rise, separate the quiet contact site of movable contact spring of upspringing during lifting in forks piece, make quiet contact site tilt and cause stationary contact and movable contact complete
Fully separating, thus the both positive and negative polarity of live wire and zero line is all disconnected connection, this completes the action of "Off", is realizing this process
When because separating forks piece to stick up effect a little, then the strength upspringing is under the briquetting spring being certainly more than movable contact spring briquetting
The strength of pressure, just can cause absolute separation, and in set machine tools, no matter how instrument vibrates, moves, knocks
Touch, even if structure member in switch has played displacement for the moment and also cannot cause down and press quiet contact site, this completes this practicality newly
The main inventive purpose one of type；
The stationary contact crawl of silver or yellow gold material is touched by the long meeting of galvanization during the long-time use of machine
Point melts, and by both weldings, so causes 1 fatal fault: machine can only leave, it is impossible to closes, will close and can only pull out
Falling power line, the integrality effect of switch completely loses, but in the utility model, under button post, pressing spring recovers bullet
The linkage of separation forks piece is lifted, is tilted the quiet contact site of movable contact spring by power, and this strength tilting is very big, can divide completely
From both weldings, prior art is all to shift up and down to switch, and separates without strength, and of the present utility model
Bullet sticks up and overcomes this critical defect.
Specific embodiment described herein is only explanation for example to the utility model spirit.The utility model institute
Belong to those skilled in the art to make various modification to described specific embodiment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
