Abstract
The utility model discloses a pull switch with state display, which is characterized in that the pull switch with state display is provided with a ratchet whose shape is different from the shape of an ordinary pull switch. Because when the pull switch is switched on or switched off, a leaf spring knocks at or does not knock at the ratchet. The 'on' or the 'off' state of the pull switch can be identified through the sound which is emitted or is not emitted when a cord of the switch is pulled. The utility model has the advantages of low cost, safe and convenient operation.
Description
The utility model discloses a kind of pulling switch with status display function.
Common pulling switch can not the residing state of display switch, and people can't discern it and are in out state or off status during power failure, use quite inconvenient.Propose to improve ratchet wheel in order to address this problem GG86209398 and GG87201077 patent application document, promptly inlay elastic or change pawl length, thereby make flexure strip different, to distinguish state or off status with the tonequality or the loudness of a sound of ratchet wheel percussion.Yet tonequality or loudness of a sound by hitting sound judge that on off state is still very difficult.
Task of the present utility model remains the problem of judging pulling switch state of living in when having a power failure that solves.
The measure of taking remains the improvement ratchet wheel.The ratchet wheel of general pulling switch all has several shapes pawl identical with size, metal spring leaf presses ratchet wheel, each backguy, and ratchet wheel is driven arm and drives, change an angle, make reed stride across a pawl, on one side there is sheet metal (electrode) on the both sides of pawl, another side does not have sheet metal, therefore every backguy once, the contact condition of reed and sheet metal changes once, also is that on off state changes once, and reed strides across pawl and clashes into the ratchet wheel sounding simultaneously.Ratchet wheel 3 outer rims of the present utility model not only have pawl 4, and have arc protruding 5, pawl and protruding being alternately distributed.To cross arc to off status reed 1 protruding from opening state, do not send knock; And from closing to the state of opening, reed 1 strides across pawl, knocks on the ratchet wheel, sends the sound.There is silent to judge switch state of living in the time of so just can be with backguy.But need to prove that actuating arm 2 is knocked by resilience when discharging backguy, opening or closing all has the sound, and this sound is caught up with the knock of stating reed and ratchet wheel and had nothing to do.If resilience sound is also calculated interior, then develop the sound twice from closing to, send out a sound from reaching to close.
In circuit, use the utility model, send or do not send the sound in the time of can be during power failure and judge the residing state of switch by means of backguy, easy to use, cheap.
Description of drawings: Fig. 1 is a profile of the present utility model.Fig. 2 is a ratchet wheel.
Embodiment: get a commercially available pulling switch, it is protruding that the half pawl on its ratchet wheel is frustrated into the arc arc, make arc protruding with distribute alternately ， And and make the protruding rotation the place ahead of arc that metal electrode be arranged of pawl, rear swivel does not have metal electrode.So just become the pulling switch of an energy show state.
Claims (1)
1, a kind of pulling switch with state demonstration belongs to the stay-supported electric switch, be used for connecting and the cut-out circuit, have in its critical piece one can driven ratchet wheel, feature of the present utility model is pawl not only to be arranged on the ratchet wheel but also have arc protruding, protruding spaced apart with pawl, there is the metal pole piece on protruding one side, and another side does not have the metal pole piece.
