Description
Technical field
The utility model relates to a kind of appliance switch, particularly a kind of push-button switch that has ratchet that is used for the control apparatus break-make.
Background technology
In various machineries and electric equipment, often need to use push-button switch, it is easy to use, if the button on the cover board, i.e. the through and off of may command power supply.The operation principle of the functor of this switch mostly is seesaw type, because volume is little, used assembling parts complexity is so assembling is very time-consuming, effort.Seesaw and contact sliding contact in the switch body not only misplace easily, break away from, and make switch out of control, and friction mutually, and shorten useful life naturally.The patent No. is 93203129, and " push switch that has driving mechanism " drives ratchet by button and rotate, make with controlling organization against conducting strip depress or lift, to reach the purpose of on/off.The control of this switch is reliable, highly sensitive, but mechanism is very complicated, exist equally parts many, be difficult for the disadvantages of assembling, and this push switch can only be used to control one road power supply, just can't use some special electric equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of new varieties of push-button switch for the appliance switch industry at above-mentioned the deficiencies in the prior art and defective.This push-button switch that has ratchet comprises the housing of being made up of base and top cover, second haptic element that has fixed contact is installed on the base with the elastic conducting strip that has moving contact, elastic conducting strip links to each other with first haptic element, elastic button is positioned at an end of top cover, the bottom of button is stretched in the housing, be supported on the base by back-moving spring, the rotating shaft two ends of ratchet are placed on base two side stands, the controll block that is positioned at the ratchet side has two circular arc contact-making surfaces of warp-wise symmetry, this circular arc contact-making surface rotates with ratchet, make elastic conducting strip depress or lift, make, closed or the disconnection of fixed contact; Dynamic and static contact on the base can be provided with two groups, and two drive the contact elastic conducting strip respectively by two controll block controls that are positioned at ratchet two sides, so that its moving contact and corresponding fixed contact clutch make the closed or disconnection of two groups of power supplys;---one logical, one disconnected---the disconnected simultaneously sequential control of the radian of the circular arc contact-making surface on the controll block being processed into greater than another controll block circular arc contact-making surface radian the two-way power supply in can control apparatus equipment, and carry out logical simultaneously.
The utility model compared with prior art, simple in structure, parts seldom, assembling easily, can be simultaneously the power supply of two functional parts on machinery or the electric equipment be carried out switching respectively with this push-button switch and controls.

Label among the figure: 1-base, 2,2 '-fixed contact, 3,3 '-moving contact, 4-top cover, 5-elastic button, 6-depression bar, 7-first haptic element, 8-back-moving spring, 9-ratchet, 10,10 '-controll block, 11,11 '-elastic conducting strip, 12,12 '-second, third haptic element.
Embodiment
Embodiment 1
As shown in Figure 1, the housing that this push-button switch is made up of base 1 and top cover 4, a pair of dynamic and static contact (3,2) is arranged on base, fixed contact 2 is fixed on the end of second haptic element, corresponding with it moving contact 3 is fixed on elastic conducting strip 11 ends, elastic conducting strip 11 is connected with first haptic element 7, and the two can process in aggregates.Elastic button 5 is positioned at an end of top cover 4, and its bottom is stretched in the housing, and is supported on the base 1 by back-moving spring 8.On base, settle a ratchet controlling organization of forming by ratchet 9, ratchet rotating shaft and controll block 10.The two ends of ratchet rotating shaft are placed on base 1 two side stands, and controll block 10 places ratchet 9 sides, and with coaxial ratchet and be processed into one, controll block has two circular arc contact-making surfaces of warp-wise symmetry, and the front end of this circular arc contact-making surface and elastic conducting strip leans.A depression bar 6 is fixed in the below of elastic button 5, and it can promote the ratchet stepping and rotate, thereby controll block is depressed the elastic conducting strip front end, makes its head moving contact and fixed contact closure, current lead-through.The resilience force of back-moving spring 8 can make elastic button reset, and presses knob down once more, and the ratchet stepping is rotated, with the controll block that ratchet rotates synchronously, when the contact-making surface of its circular arc broke away from elastic conducting strip, elastic conducting strip lifted, thereby moving contact is separated with fixed contact, and electric current disconnects.One group of on/off of present embodiment may command.
Embodiment 2
Two groups of dynamic and static contacts can be set on base, and fixed contact 2,2 ' is separately fixed at second, third haptic element 12,12 ' end.Be separately fixed at two elastic conducting strip of placing side by side 11,11 ' ends with fixed contact 2,2 ' the corresponding moving contact 3,3 ', the root of elastic conducting strip 11 and elastic conducting strip 11 ' all links to each other with first haptic element 7, and can process in aggregates.The controll block 10 of the ratchet controlling organization of present embodiment and controll block 10 ' place ratchet 9 two sides, and it is processed into one with coaxial ratchet, and they can control two groups of power supplys.All the other structures are identical with embodiment 1.The radian of the circular arc contact-making surface of controll block 10 ' can be greater than the radian of the circular arc contact-making surface of controll block 10, as shown in Figure 2, their circular arc contact-making surfaces all break away from elastic conducting strip 11 and elastic conducting strip 11 ', elastic conducting strip lifts, two groups of dynamic and static contacts break away from, and two groups of power supplys all disconnect.Press down elastic button, depression bar 6 promotes the ratchet stepping and rotates, and controll block 11 and controll block 11 ' are in position shown in Figure 3, and controll block 10 is separated with conducting strip 11, conducting strip 11 lifts, the moving contact of its end and fixed contact break away from, and this group electric current disconnects, meanwhile, because the camber ratio of the circular arc contact-making surface of controll block 10 ' is bigger, therefore still compress mutually with conducting strip 11 ', this still conducting of group electric current is to form the operating state that two groups of electric currents one logical break.Once more elastic button is pressed down, made controll block 10 and controll block 10 ' be in position shown in Figure 3, their contact-making surface all compresses with elastic conducting strip 9 and elastic conducting strip 9 ', makes that elastic conducting strip is depressed, dynamic and static contact closure, thus two groups of current lead-through.Present embodiment is with two groups of dynamic and static contacts, a controll block respectively is set, can controls two groups of power supplys in a certain machinery or the electric equipment simultaneously with this kind push-button switch, to satisfy the needs of different user at the ratchet side.
