Introduction of parameters and application scope of side-press light-touch switch
The parameters and scope of use of the side-tap switch are introduced to you today. What are the specific characteristics? Please see below.
Next is the introduction of the relevant parameters of the side-press light-touch switch.
More and more people are using side-press light switch at present, which leads to different sizes and sizes. So what characteristics do we need to know when we use side-press light switch? If you need to know the types and characteristics of side-press switches, you might as well look down. Before introducing the parameters of the side-press switch, we first introduce the types of the bottom-press switch. The side-press switch is a relatively small key switch in the light-touch switch. The minimum size of the small side button is 2x4, and the largest is generally 2x4 side-press. The base and handle are between 3.5 and 3.75 mm in height. On the small side, there are two types: bracketed and non-bracketed, with positioned Full-wrapped feet and so on.
Next, we will introduce its characteristics from the types of side-tap switches.
The advantage of side-press light switch with bracket can be well fixed with the product, which does not mean that there is no good fixing without bracket. According to the design of products, some products have bracket position, and some products directly welded on the PCB board will also have a good fixing effect. The positioning column is also a good fixing function for the side press switch. The advantages of side-press switch are lightweight, smaller occupancy, convenient use and good fixed performance. The frequency of use is higher than other light-touch switches, and it will have its shadow in life. For example, the side-press switch is also used in the automobile remote control, which is more reliable in quality and safety. The side-press switch is a key switch that emerges slowly after the light-touch switch.
Attention should be paid to tapping the switch with side keys:
The metal shrapnel inside the side-touch switch generally belongs to the elliptical pot disc. In the process of using the metal shrapnel, there is a special point to pay attention to, which should not exceed the pressure it bears. It is likely to be damaged or not to press continuously. It may also fail or damage the service life of the metal shrapnel, and the metal shrapnel should not exceed the pressure it bears. The surface of the wafer can not be covered with an insulating material (oxide), otherwise the conductivity will be affected. The sealing property of the side touch switch is not particularly good, and generally can not play a long-term waterproof role, so long-term use in water is easy to be damaged.
