Description

Fixed base of switch and switch assembly Technical Field The utility model relates to the technical field of switches, in particular to a fixed base of a switch and a switch assembly. Background In electronic devices, household appliances and various mechanical control devices, push-button switches are used as a very critical operating element, and the performance of the fixed base of the push-button switch has a very important influence on the stability and the service life of the whole switch. Currently, most of the fixed bases of push button switches are made of metal materials. The metal base can effectively bear various pressure and impact force generated in the frequent use process of the push button switch by virtue of the excellent strength and stability of the metal base, so that the normal function of the switch is ensured. However, there are also some significant disadvantages to such metal bases. On the one hand, the relatively high density of the metal material results in relatively high quality, which is a significant disadvantage for some application scenarios with strict requirements on the light weight of the equipment, and on the other hand, the relatively high material cost of the metal material increases the overall cost of the product to some extent. In addition, there are also fixed bases for push-button switches made of plastic materials. The plastic base has the remarkable advantages of light weight, low processing cost and the like, and can effectively reduce the overall weight and the production cost of the product, so that the plastic base has certain advantages in some application scenes sensitive to cost and weight. However, the strength of the plastic material is relatively low and the durability is also relatively poor. In the long-term use process, the plastic base is easy to deform and damage, so that the button switch is not firmly fixed, and the normal use of the button switch is influenced. Especially in some high-strength use occasions, such as industrial control equipment, frequently operated electric appliances and the like, the service life of the plastic fixing base is often difficult to meet the requirements and needs to be frequently replaced, so that the maintenance cost is increased, and a plurality of inconveniences are brought to users. In summary, the prior art of the fixed base for a push button switch has a certain limitation in material selection, and cannot meet various requirements of high strength, light weight, low cost, long service life and the like. Therefore, it is particularly urgent and necessary to develop a new fixing base structure to overcome the shortcomings of the prior art. The matters in the background section are only those known to the inventors and do not, of course, represent prior art in the field. Disclosure of utility model In view of one or more of the drawbacks of the prior art, the present utility model provides a fixed base of a switch, comprising: the metal insert comprises a first connecting part, a second connecting part and a third connecting part, wherein the first connecting part is provided with a first connecting hole, the second connecting part and the third connecting part are respectively connected to the outer side of the first connecting part, the second connecting part is provided with a second connecting hole, the third connecting part is provided with a third connecting hole, and The non-metal frame is coated on the outer side of the metal insert, and a first through hole, a second through hole and a third through hole are formed in the non-metal frame, wherein the first through hole is aligned with the first connecting hole, the second through hole is aligned with the second connecting hole, and the third through hole is aligned with the third connecting hole.
