Electric shock in the touch switch is very important. Is it better to touch the switch with an electric shock? Now let's take a look at this problem together.

The light touch switch looks at the shell data first. The first switch brands in the market usually choose PC material, PC material also known as bullet proof adhesive. The characteristics of impact resistance, high temperature resistance and non discoloration are important for controlling electrical switches.
Next, look at the contact point, that is, the contact point of the conductive parts in the process of the Dongguan light touch switch. One must look at the details (the bigger the better), and the two depends on the data.
There are three main contacts, silver nickel alloy, silver cadmium alloy and pure silver. Silver nickel alloy is the contact information of contrast ambitions now. It has good conductivity and hardness, and does not oxidize or rust easily.
Silver cadmium alloy contacts are also good, but the cadmium element is attributed to heavy metals, one side is harmful to the human body. On the other hand, the blending of silver is not too ambitious. It will form small cadmium metal particles on the contact surface, and may pull out the arc when conducting the conduction. Pure silver is not suitable for contact, and the conductive function is really good, but pure silver is soft and easy to oxidize (like silver jewelry will be blackened at a long time). The texture is soft, and the contacts are distorted when the switch is too many. If the rust is oxidized, the conduction function will be much worse. The rust point is also simple and hot, and it is very easy to burn the contacts.
Third see the light touch switch structure. Now the first is the large panel style, the appearance and feel are better than the thumb type. The biggest problem of the thumb type is the simple clamping, because the torque comparison is short, the switch action amplitude contrast is small, the spring is slightly soft or a good point, all may cause the switch to hold.
