Basic structure of the switch

Basic structure of the switch

Basic structure of the switchThe simplest switch has two pieces of metal called "contacts". When the two contacts are in contact, the current forms a loop, and when the two contacts are not in contact, the current opens. When choosing the contact metal, it is necessary to consider its degree of resistance to corrosion, because most metals will form an insulating oxide after oxidation, making the contact unable to work properly. The selection of contact metal also needs to consider its electrical conductivity, hardness, mechanical strength, cost and whether it is toxic or not. Sometimes corrosion-resistant metal is plated on the contacts. It is generally plated on the contact surface of the contact to avoid affecting its performance due to oxide. Sometimes non-metallic conductive materials, such as conductive plastics, are also used on the contact surface. In addition to the contacts, there are also movable parts that make the contacts conductive or non-conductive. Switches can be divided into lever switches, key switches, and rocker switches depending on the movable parts. The movable parts can also be Other types of mechanical linkage.
