Heat-resisting switch

Abstract

The invention relates to the technical field of switches, and discloses a high temperature resistant switch, comprising a mounting box, the surface of the mounting box is provided with an external connection hole, and the inner side of the mounting box is fixedly installed with a fixing hole, and the fixing hole is connected with a A mounting plate, and a circuit board is fixedly installed inside the mounting plate, a nylon back seat is fixedly installed on the surface of the installation plate, and a switch terminal is fixedly installed on the surface of the nylon back seat. The high-temperature-resistant switch adopts a detachable switch structure, which is convenient for maintenance and replacement of parts. By using high-temperature-resistant material for the junction point, it can prevent the junction point from being overheated due to high power and cause fire. By setting the detector and alarm The device can realize temperature and personnel detection, detect and alarm abnormal conditions, and can realize two modes of automatic and manual control. The structure is simple, the operation is convenient, and it has a high market promotion prospect.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a high temperature resistant switch. Background technique [0002] The word switch is interpreted as on and off. It also refers to an electronic component that can open a circuit, interrupt the current flow, or cause it to flow to other circuits. The most common switches are human-operated electromechanical devices that have one or more electrical contacts. The "closed" of the contact means that the electronic contact is conductive and allows current to flow; the "open" of the switch means that the electronic contact is not conductive and forms an open circuit, and the current is not allowed to flow. The simplest switch has two chip names The metal called "contact" makes the current form a loop when the two contacts are in contact, and the current is open when the two contacts are not in contact. When selecting the contact metal, it is necessary to consider its corrosion resi...

AI Technical Summary

Problems solved by technology

In addition to the contacts in the switch, there will also be movable parts to make the contacts conductive or non-conductive. The switch can be divided into a lever switch (Toggle switch), a key switch, and a rocker switch (Rockerswitch) according to the different movable parts. The movable part can also be other types of mechanical linkages, but the switches commonly used at present cannot withstand high temperatures, and are easy to ignite and cause fires under high temperature conditions.
