Sub- contact.The " closed " (closed) of contact represents electronic contact conducting, it is allowed to which electric current flows through；" open circuit " (open) table of switch
To show that electronic contact is not turned on forming open circuit, do not allow electric current to flow through, simplest switch has two metals for being named as " contact ", and two
Electric current is set to form loop, current open when two contacts do not contact during contact.It need to consider that its confrontation is rotten during from contact metal
The degree of erosion, because the oxide of insulation can be formed after most metals oxidation, make contact can not normal work.From contact gold
Category it is also contemplated that its electrical conductivity, hardness, mechanical strength, cost and whether the factor such as poisonous.Anti- corruption is electroplated on contact sometimes
Lose metal.The contact surface of contact can be typically plated in, to avoid influenceing its performance because of oxide.Sometimes contact surface can also use non-
The conductive material of metal, such as conductive plastic.In switch in addition to contact, also having movable piece makes contact turn on or be not turned on,
Switch can not be all to be divided into lever switch (Toggle switch), key switch, ship type to switch (Rocker according to movable piece
Switch) etc., and movable piece can also be the mechanical linkage of other patterns, but currently used switch can not bear high temperature,
Easily light in the case of a high temperature and cause fire.
