Abstract
The utility model relates to a light touching type switch which is mainly composed of a metal main body support frame, a circuit plate, a key, a key support frame and a surface key. The utility model is characterized in that one key or a plurality of keys are arranged on the key support frame; the key can move from left to right on the key support frame like a seesaw; the surface key, the key and the circuit plate horizontally cling. The utility model has the characteristics of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of switching device, refers more particularly to a kind of touch switch device that uses on wall.
Background technology
Most in the market touch switch mainly is made up of circuit board, main body rack, button and key support, this touch switch is established on the wall basically, and be provided with two grades of open and close, be about to button to a direction by being out that another opposite direction is then for closing.After depressing, this button can reset, promptly to make whole keytop all be on the horizontal plane, otherwise can make whole button uneven, promptly not attractive in appearance, be unfavorable for operation simultaneously, in order to achieve the above object, existing method is to be provided with metal clips between button and key support, after making that each button is pressed, utilize the elastic force effect of metal clips to make button reply.The weak point of this structure is: each button all will be provided with the answer shell fragment, the cost height, and craft precision requirement simultaneously is very high, adds comparatively to bother man-hour.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and the touch switch that a kind of cost is low, be easy to process, can guarantee the button abswolute level is provided.
The utility model realizes that in the following way the utility model mainly is made up of metal master support, circuit board, button, key support and surperficial button.Be provided with one or more buttons on key support, button is the left-right symmetric structure, and both sides, position, intermediate portion are provided with cylinder-shaped shaft; Be provided with one or several and the corresponding axle bed of button on key support, axle bed is provided with axis hole, and the cavity of two axle bed central authorities can hold button, and the cylinder-shaped shaft on the button places axis hole, and button can be with this axle center left-right rotation.The button upper end is a horizontal plane, is provided with two cavitys, and in surperficial button was nested in, the button upper end was level with surperficial button and is close to shape; Both sides, button lower end are provided with cylindrical contact, are level with button shell fragment on the circuit board and are close to.When surperficial button is stressed, can drive the action that opens or closes by the realization of the contact on the key stroke circuit board.
The utility model with respect to prior art say have cost low, be easy to process, can guarantee that the button abswolute level is beneficial to the characteristics of operation.

Embodiment
Now in conjunction with the accompanying drawings, embodiment of the present utility model is described in detail in detail:
As shown in Figure 1, the utility model mainly is made up of metal master support 1, circuit board 2, button 3, key support 4 and surperficial button 5.Metal master support 1 below is provided with circuit board 2, which is provided with key support 4, and key support 4 is provided with several buttons 3, is with surperficial button 5 on button 3.
As Fig. 2, shown in Figure 3, on key support 4, be provided with one or more buttons 3 as required, button 3 is the left-right symmetric structure, is provided with cylinder-shaped shaft 9 in the both sides, middle part; Button 3 upper ends are horizontal plane, are provided with two cavitys, and in surperficial button 5 was nested in, button 3 upper ends and surperficial button 5 were level and are close to shape.The both sides of button 3 and circuit board 2 contacted positions respectively have a groove 8, and the protruding seat 6 of a projection is arranged in the outside of groove 8, are provided with two cylindrical contacts 7 in the bottom of protruding seat 6.Cylindrical contact 7 contacts with button shell fragment 32 on the circuit board 2.On key support 4, be provided with one or several and button 3 corresponding axle beds 10, axle bed 10 is provided with axis hole 11, the cavity of two axle bed central authorities can hold button 3, cylinder-shaped shaft on the button 3 is placed axis hole 11, can make button 3 location, and can rotate around the axle center as seesaw.
When work, press the surperficial button 5 of switch, it is downward to drive button 3, at this moment by the button shell fragment 32 on the cylindrical contact 7 downward striking circuit boards of button 3 bottoms, thereby finishes action response one time.Because button 3 both sides have groove, make button 3 can produce elasticity when stressed, when striking, by button shell fragment 32 application of forces of cylindrical contact 7 on circuit board, send clear and melodious sound in the time can making in striking under the elastic force effect, and good hand feeling is arranged.
Because button (3) upper end is a horizontal plane, is provided with two cavitys, in surperficial button (5) was nested in, button (3) upper end was level with surperficial button (5) and is close to shape; Button (3) both sides, lower end are provided with cylindrical contact (7), are level with button shell fragment (32) on the circuit board (2) and are close to.So after finishing keystroke, whole switching device still keeps the abswolute level state.
Claims (2)
1. touch switch, mainly form by metal master support (1), circuit board (2), button (3), key support (4) and surperficial button (5), it is characterized in that: key support (4) is provided with one or more buttons (3), button (3) is the left-right symmetric structure, and both sides, position, intermediate portion are provided with cylinder-shaped shaft (9); On key support (4), be provided with one or several and the corresponding axle bed of button (3) (10), axle bed (10) is provided with axis hole (11), the cavity of two axle bed central authorities can hold button (3), cylinder-shaped shaft (9) on the button (3) places axis hole (11), and button (3) can be with this axle center left-right rotation.
2. a kind of touch switch key device according to claim 1 is characterized in that: button (3) upper end is provided with two cavitys for horizontal plane, and in surperficial button (5) was nested in, button (3) upper end was level with surperficial button (5) and is close to shape; Button (3) both sides, lower end are provided with cylindrical contact (7), are level with button shell fragment (32) on the circuit board (2) and are close to.
