Abstract
The utility model discloses a light-emitting type button switch for household electric appliances, which comprises a button part. The button part comprises a button. The button switch is characterized in that a transparent positioning column is sleeved outside the button. The positioning column is connected with a button hole arranged on the button base of the switch and used for the arrangement of the button. The positioning column for positioning the button is made of transparent material. The bottom of the button is provided with a backlight source and the top of the button is provided with a pattern and other function display information. Since the positioning column is made of transparent material, the light emitted from the backlight source is enabled to conveniently pass out of the positioning column. In this way, the information can be normally displayed at the top of the button. When the pressing contact of the button is to be mounted onto the button base, the mounting direction of the pressing contact is limited by two differently sized positioning convex blocks. Therefore, the button is prevented from being on backwards. The positioning column and the button base are in clamped connection in a detachable manner, so that the switch assembly is convenient to assemble and disassemble.

Fig. 2 is the decomposition texture schematic diagram of button part of the present utility model;
Fig. 3 is the exploded structural representation of push-button switch of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Referring to Fig. 1-Fig. 3, for an illuminated push-button switch for household electrical appliance, as be used on the panel of range hood, comprise button part 1 and switch sections 2, button part 1 is arranged on switch sections 2, and switch sections 2 comprises the push-button socket 21 for button part 1 is set.
Button part 1 comprises button 11, can make with metal, is set in the reference column 12 of button 11 peripheries, can make with the plastics of printing opacity.Button 11 and reference column 12 are all the cylindrical of hollow, so that in button 11 is located in, the front end of button 11 is exposed to reference column 12, while pressing button 11, button 11 relative positioning posts 12 are done axial movement.
The bottom of reference column 12 is provided with radially outer engaging projection, and engaging projection comprises that week, upwards the first engaging projection 121 spaced apart and the second engaging projection 122, the first engaging projections 121 and the second engaging projection 122 were all the shape of fan ring.
On push-button socket 21, offer the button hole 211 mating with reference column 12, on the sidewall of button hole 211, offer and the slot that engages projection form fit, slot also comprises the first slot 212 and the second slot 213, the first slot 212 engages the form fit of projection 121 with first, the second slot 213 engages the form fit of projection 122 with second.Thus, in the time that reference column 12 is inserted into above from the back side of push-button socket 21, when two engagings projections and slot correspondences must be snapped in, just can connect.On the first engaging projection 121 and the second engaging projection 122, be equipped with projection 123, the upper surface of projection 123 can be the arcwall face of inclination, the madial wall of the first slot 212 and the second slot 213 is provided with corresponding draw-in groove 214, when thereby reference column 12 inserts, thereby can snap onto in draw-in groove 214 reference column 12 and push-button socket 21 are fixed along the curved surfaces of projection 123, upwards all carry out spacing to reference column 12 in axial and footpath.
