Description

Have key and touch the snap switch of handle and the decoration technology that key touches handle

The present invention relates to one and have the decoration technology that key touches the snap switch and the key shake-up handle of handle.

For example, in Japanese patent gazette No.10-326539, we have known the relevant situation that key touches the snap switch of handle that has, and this switch comprises a housing that holds one group of contact, and one is supported on the housing and rotating button.In a single day this button is depressed, and it will make the contact be in one of two condition and keep this state to be pressed once more up to button and just can change.Greater than the key of button touch handle be positioned at button above, his end is supported on the housing with rotating shaft, revolts elastic force and strikes button as knocking piano key.This communique has disclosed a kind of with the method for internal cast technology at the front of handle decorative color mark.The transfer printing film that scribbles the seal China ink above the use of internal cast technology is a kind of is put into injection mould with the plastics that form handle, forms pattern thereby will print black being transferred on the handle of casting and at handle.Use this internal cast technology will print China ink accurately be transferred on the handle not difficult, yet, reduced production efficiency and increased production cost of products, in addition, transfer printing film itself has also additionally increased cost.

In view of the above problems, the present invention has finished and proposed one improvedly has a snap switch that key touches handle, not only low cost of manufacture but also ornamental colour-coded is made in success exactly.

According to the present invention, switch comprises a housing that holds a fixed contact at least; A moving contact that is meshed with fixed contact; One is supported on the button that can move on the housing between normal position and compression position.Because the effect of return spring, this button can be biased into the normal position.Button is connected with moving contact by pole, and when pressing button, the toggle spring on the pole just produces snap-action action and moving contact and fixed contact are meshed and keeps this state up to pressing the button once more.For the biasing force that makes button antagonism back-moving spring is pressed onto compression position from the normal position, key shake-up handle one end is supported on the housing and with button by rotating shaft and meshes.Handle is made by plastics, with plastics reaction is formed with colour-coded by laser beam irradiation on it in the front of handle.Thereby colour-coded not only is replicated on the handle exactly, and lower than adopting the traditional handicraft cost.In addition, because the colour-coded that forms with laser radiation can keep the longer time, thereby improved the durability of handle mark.Ornamental colour-coded is formed by plastics and laser charing, therefore, and the smooth touch sense that can not destroy handle of handle surfaces.

Ornamental colour-coded can be designed to have the band of many parallel lines, and can track simultaneously by the multiple laser bundle that the single beam laser source generates, therefore every straight line can duplicate with more weak single beam laser source, and the straight line that forms is smooth has a good touch sense.

Handle comprises that a transparent title window exposes in the front portion of handle; The lid that above-mentioned window is sealed places in the middle of window and the lid title board.Title window and lid constitute a special unit and are convenient to title window and handle assembling, and the title window writes on the purposes or the purpose of switch on the title board in order to indication.

The title window is made the rear portion be round concave surface and allow the title board easily to slide into and skid off, more desirable like this.In addition, the rear surface of title window has stud that the title board is fixing with it, prevents owing to the electrostatic interaction that produces between the two makes the title board on the title window rear surface that beyond thought adhesion take place.

The title window can with framework with its firmly frame live, be installed in the hole on the handle, this framework is ultrasonically welded on the handle at its periphery place.Like this, the title window just is fixedly mounted on the handle easily.Handle can be convenient to and the button engagement with the actuator cast solid, guarantees that handle accurately is connected with button, realizes reliable switching manipulation.

Front surface at handle has a shake-up miter guide.Handle one end is supported on the housing with rotating shaft, and it is outstanding at the handle other end to touch miter guide, and like this, even in the environment of dark, the user also can be easy to confirm to knock the tram of switch.

Switch designs becomes standard size, and such three switches just can adjacently in twos be installed on the standard fixed frame.An installing hole is arranged on the fixed mount, and the front end by this hole switch just can expose so that handle and button are coupled together.Use fixed mount switch can be installed on the wall of building or family; And for for the purpose of attractive in appearance, fixed mount has on the panel cover in hole with the surface; Hole on the panel should be bigger so that can hold the handle that links to each other with switch respectively than the hole on the fixed mount.Handle make first kind of standard size in case three independently handle can be adjacent in twos be placed in the panel hole.First kind of standard size by the handle of three separation the size when placed side by side determine and the hole taken fully.When adorning two switches on the fixed mount of identical standard and identical panel is installed on fixed mount, handle is made second kind of standard size, this standard size by two handles the size when placed side by side determine, and take the whole space of panel hole.In addition, when only adorning a switch on the identical fixed mount and on fixed mount identical panel is installed, handle is made the third standard size, and this size is determined by the size of a handle, and made it to take the space in whole hole.Therefore, no matter two or three switches are installed on the fixed mount, all adopt identical panel.

Switch preferably comprises a lamp, and light is in order to indication moving contact disengagement situation on the fixed contact.Handle has light miter guide guiding light to shine on the front surface of handle to make the user confirm on off state easily, thereby can have gauffer can increase the visible range of light in order to divergent rays on the light miter guide.

In addition, use prism and cooperate collected light with the light miter guide and light is directed on the indicating device, and this indicating device is fixed on the front end of light miter guide and expose at the handle front surface.The front end and the indicating device of prism match, and its rear end extends to form a light receiving surface wideer than the vertical size of indicating device on the handle vertical direction.Prism is welded to it on handle with method for ultrasound welding, and make and have at least a part relative in the wide optical receiving surface with switch lamp, therefore even indicating device had situation about departing from the lamp of vertical direction and switch when handle was installed, the light of lamp can gather together and by prism light is directed on the indicating device by wide light receiving surface.

In order to form the decoration band of parallel colored rectilinear(-al), the laser beam folk prescription is neatly smooth to the axial end that scanning on handle forms straight line and every straight line.In addition, laser beam also can bilateral scanning, promptly in order to form colored straight line fast, scanning before and after the laser beam.Therefore, in order to improve the efficient (each band is by many colored rectilinear(-al)s) that forms a plurality of bands, adopt a plurality of laser beam generators once to finish a plurality of bands.
