Description
Technical field
The utility model belongs to the electric switch technical field, is a kind of combination interlocking key switch with housing, buckle, spring, button.
Background technology
In Chinese patent literature, the patent No. is 96237513.6, name is called have been introduced a kind of combination button switch in the utility model patent specification of combination button switch and has comprised button, the tower spring, clamp, buckle, the button spring, static contact, movable contact spring, housing and case lid, be respectively equipped with the guiding slotted eye that makes the clamp oriented movable on housing and the case lid, clamp is arranged in the gathering sill, can move up and down, buckle is arranged in the sliding tray of housing and between the case lid, can in sliding tray, move back and forth, on housing, be provided with the contact holddown groove, static contact and movable contact spring all are fixed in the contact holddown groove, clamp moves downward, can push up movable contact spring, the contact of movable contact spring is contacted with static contact.This switch is to be used for being installed in electrical equipment, on electric fan, is used to switch the gear of electric fan, to regulate the wind speed of electric fan.When any one interlocking button is pressed, the running of all can switching on of the main motor of electric fan.On electric fan, also have a rotating vane that drives by less stand-by motor, be used for the wind that electric fan blade blows out is broken up.Stand-by motor is to control break-make by an independent auxiliary switch.When the main motor of electric fan is combined after key switch cuts off, as long as the auxiliary switch closure, stand-by motor still can drive the rotating vane rotation, that is to say that button switches, auxiliary switch can not be connected with it, and this is nonsensical for electric fan uses, can only consumed power.
The utility model content
The purpose of this utility model is to provide a kind of to be had and can switch the modifier key of connecting with any one interlocking button, and only under the situation that the interlocking button is connected, modifier key just can be controlled break-make, thereby realizes the combination interlocking key switch of electrical interlock.
For realizing the purpose of this utility model, described combination interlocking key switch, include shell, be arranged on the buckle that can slide in the shell, drive the interlocking button that buckle slides, be provided with the buckle spring between buckle and the shell, the interlocking button is provided with the card arm that extends to buckle, described buckle is provided with the button hook that can catch on the card arm, be provided with static contact in the shell, side at buckle is provided with the interlocking movable contact spring that keeps isolation with static contact corresponding to the interlocking key position, after being provided with and pressing, the interlocking button can withstand on the compression leg that on the interlocking movable contact spring it is contacted with static contact, be provided with between interlocking button and the shell make that the interlocking button upsprings by key spring, described buckle side also is provided with the interlock plate that passes on the buckle spring, be provided with top flat at the corresponding button hook of interlock plate position, the forward position of top flat is in colluding in the groove of button hook, when the card arm of interlocking button is pressed, the card arm can withstand on button hook and the top flat, buckle and interlock plate are slided, be provided with the interlock plate movable contact spring that keeps isolation with static contact in the shell, on the interlock plate, be provided with and push up interlock plate movable contact spring, the interlock plate top that interlock plate movable contact spring is contacted with static contact.
Because the buckle side also is provided with the interlock plate, linking, plate is parallel with buckle to be abutted in together, when the card arm on the interlocking button is pressed, can withstand on the top flat, the interlock plate is slided to a side, interlock plate top on it then withstands on the interlock plate movable contact spring, interlock plate movable contact spring is moved, until contacting with static contact to the static contact direction.Owing to be equipped with top flat, so each interlocking when being pressed, all can make interlock plate movable contact spring contact with static contact by strong downwards in each position of moving downward of card arm.Because the forward position of top flat is in colluding in the groove of button hook, when the card arm of interlocking button was pressed, the card arm can withstand on button hook and the top flat, and buckle is slided, and the interlock plate is slided.And when the card arm enter button hook collude in the groove after, buckle can resilience under the precompressed elastic force effect of buckle spring, make and collude groove and snap in the card arm, the interlocking button is caught on, the connection that keeps this key switch, at this moment, on one side since the interlock plate only propped up by the card arm to backing down the back can't resilience, thereby after having kept interlock plate movable contact spring to be pushed with the contacting of static contact.Form a kind of interlock relation in parallel between interlocking key switch and interlock plate movable contact spring and the static contact.This has only under the situation of interlocking key switch connection in electric connection control, and interlock plate movable contact spring just keeps connecting with static contact, and Chuan Jie switch just has the effect that break-make is controlled after this, otherwise has only the effect of disconnection.
