Description

Safety switch

Technical Field

The invention relates to the technical field of switches, in particular to a safety switch.

Background

The term switch is to be interpreted as open and closed, it also refers to an electrical component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common type of switch is an electromechanical device that is operated by a person, in which there are one or more electrical contacts, and a "closed" contact indicates that the electrical contact is conductive and current is allowed to flow, and an "open" switch indicates that the electrical contact is non-conductive and forms an open circuit and does not allow current to flow.

The simplest switch is composed of two pieces of metal called 'contacts', the current forms a loop when the two contacts are in contact, the current is open when the two contacts are not in contact, the degree of corrosion resistance of the metal is required to be considered when the metal of the contact is selected, because most of the metal forms insulating oxide after oxidation, the contact cannot work normally, the metal of the contact is selected, the factors such as conductivity, hardness, mechanical strength, cost, toxicity and the like are also required to be considered, corrosion-resistant metal is plated on the contact sometimes and is generally plated on the contact surface of the contact, and the performance of the metal of the contact is prevented from being influenced by the oxide. Non-metal conductive materials such as conductive plastics are sometimes used for the contact surface, and in the switch, besides the contact, there is also a movable part to make the contact conductive or non-conductive, the switch can be classified into lever switch, key switch, ship switch, etc. according to the difference of the movable part, and the movable part can be other types of mechanical links.

Present switch is not single for guaranteeing its function, sets up three-pin socket and two-pin socket on the switch usually, also can supply power for electrical apparatus when guaranteeing its ability control circuit, and when three-pin socket and two-pin socket supply power for electrical apparatus on the switch, can produce a large amount of heats usually, and the conflagration can take place for the misuse, and the switch all passes through the fix with screw on the wall in addition, overhauls and is very inconvenient when changing.
