Specific embodiment

The utility model will be further described with reference to the accompanying drawing.

With reference to the accompanying drawings shown in 1, the touch switch of the utility model comprising button 1, support plate 2 and be set to support plate 2 Microswitch 3, circuit board 4, the button 1 swing is connected in support plate 2, and microswitch 3 is connect with circuit board 4.Wherein, The button 1 is equipped with as button 1 swings and touch the longitudinal elasticity swing component of microswitch 3, longitudinal elasticity swing component Upper end is connect with 1 bottom of button, and the lower end of longitudinal elasticity swing component is connect with the inner bottom surface of support plate 2.

Wherein, the longitudinal elasticity swing component includes connecting spring 5, connector 6, and the upper end of the connector 6 presses Connecting spring 5, the lower end of connector 6 are connected to the inner bottom surface of support plate 2, and connector 6 is swung and microswitch 3 with button 1 Abut against, the connecting spring 5 be assemblied in button 1 bottom and elastic reaction on connector 6 so that connector 6 reset and with it is micro- Dynamic switch 3 separates.

That is, needing the elastic force that enough external force overcomes connecting spring 5, together when user presses the touch part of lower button 1 When so that connector 6 with button 1 swing and touch microswitch 3, allow user using switch when have touch sense, can judge Whether switch is by control on-off, it is ensured that the use quality of switch.

It referring to shown in Fig. 2 to Fig. 3, further refines, the connector 6 is switch pellet.Switch upper end and the company of pellet The connection of spring 5 is connect, the inner bottom surface of support plate 2 is equipped with the convex edge 8 being slidably connected with the lower end of switch pellet.The convex edge 8 is equipped with Highest order 81, raw bits 82 put position 83, and the position 83 of putting is set to close to 8 side of the convex edge of microswitch 3, raw bits 82 Set on put symmetrical 8 other side of convex edge in position 83.Moreover, the lower end of the switch pellet swings compression connection with button 1 It is successively slid onto from raw bits 82, highest order 81 while spring 5 and puts position 83 and abutted against with microswitch 3, switch pellet Lower end separates under the elastic reaction of connecting spring 5 with microswitch 3.

In use, the touch part to button 1 applies enough external force, make the touch part of button 1 toward lower swing.Switch pellet As button 1 is swung, so that the lower end of switch pellet is up slid onto highest order 81 from the raw bits 82 of convex edge 8, this process is needed It gradually big external force to be controlled.Position is put along convex edge 8 is past after highest order 81 of convex edge 8 are crossed in the lower end of switch elasticity 83 glide, and the external force of the needs of this process gradually becomes smaller, and the lower end of switch elasticity can also be rocked to and puts position 83 and and fine motion Switch 3 is abutted against.Microswitch 3 will transmit a signal to circuit board 4 after being closed, and handled by circuit board 4 and made corresponding Switch control functions are realized in movement.It also allows user to feel using when switch with touch at this time, whether can judge microswitch 3 Be triggered closure, then without external forces, 5 elastic reset of connecting spring.The elastic reaction of connecting spring 5 is being opened Pellet is closed, switch pellet is promoted to separate as button 1 is swung with microswitch 3.

In addition, the support plate 2 is equipped with the reset spring 10 so that the holding horizontality of button 1, reset spring 10 divides Cloth is between support plate 2 and the connection of the touch part of button 1.

After user unclamps hand, in the case where no application external force, touch of 10 elastic reaction of reset spring in button 1 In portion, the touch part of button 1 resets.During button 1 is swung, enough external force is also provided and allows the lower end of switch pellet from convex edge 8 Position 83 of putting slide onto highest order 81 and slide down onto raw bits 82, realize switch pellet lower end separated with microswitch 3, raising The Stability and dependability of operation guarantees the using effect of switch.Meanwhile make button 1 keep horizontality, it is ensured that switch it is whole Body uses beautiful.

Referring to shown in Fig. 2, second embodiment, the button 1 is equipped with the connection shaft 7 that adaptation connecting spring 5 is installed.It is described Connection shaft 7 can be integrally formed with button 1；Alternatively, connection shaft 7 and the split type setting of button 1.Improve structural stability with can By property, it is ensured that the elastic reaction of connecting spring 5 guarantees the use quality of switch.

Referring to shown in Fig. 4 to Fig. 5,3rd embodiment, with it is above-mentioned the difference is that: the connector 6 is sliding piece, is dialled The upper end of movable plate presses connecting spring 5, and the inner bottom surface of support plate 2 is equipped with the groove 9 being located by connecting with the lower end of sliding piece.Institute It states the upper end of sliding piece and connecting spring 5 and past 3 side of microswitch is compressed as button 1 is swung for fixed point with the lower end of sliding piece To swinging and abutting against with microswitch 3, the upper end of sliding piece is separated under the elastic reaction of connecting spring 5 with microswitch 3.

Similarly, in use, the touch part to button 1 applies enough external force, make the touch part of button 1 toward lower swing. Sliding piece with button 1 swing so that the upper end of sliding piece with the lower end of sliding piece be pinpoint toward fine motion direction swing and with it is micro- Dynamic switch 3 is abutted against.Microswitch 3 will transmit a signal to circuit board 4 after being closed, and handled by circuit board 4 and make phase It should act, realize switch control functions.Also it allows user to feel using when switch with touch, can judge microswitch 3 whether Be triggered closure.Then, under the action of without external force, 5 elastic reset of connecting spring.The elastic reaction of connecting spring 5 is being stirred On piece promotes sliding piece to separate as button 1 is swung with microswitch 3.

Above-mentioned specific embodiment is only the preferable specific embodiment of the utility model effect, all touchings with the utility model The identical or equivalent structure of moving type switch, it is within the protection scope of the present utility model.
