Background
The simplest switch has two pieces of metal called "contacts", which make the current form a loop when they are in contact and open when they are not in contact. The contact metal is selected with regard to its degree of corrosion resistance, since most metals oxidize to form insulating oxides that prevent the contact from functioning properly. The contact metal is selected in consideration of its conductivity, hardness, mechanical strength, cost and toxicity. Corrosion resistant metals are sometimes plated on the contacts. The contact surface is typically plated to avoid oxide degradation of the contact. Non-metallic conductive materials, such as conductive plastics, are sometimes used for the contact surfaces. In the switch, a movable element may be used to make the contact conductive or non-conductive, the switch may be classified into a lever switch (Toggle switch), a push switch (pushbutton switch), a Rocker switch (Rocker switch) and the like according to the difference of the movable element, and the movable element may be another type of mechanical link.
