Mechanical type tilting motion switch

Abstract

The switch is composed of body case, micro switch and heavy ball. There is upper cavity, conic cavity and lower cavity connected in the body case. Passing through body case, electric lug plate of the micro switch is extended out of the body case. Position of the bunter of the micro switch is faced to the conic cavity. An upper cover seals cavity mouth. The disclosed switch can turn off circuit in any oblique direction in 360 degrees. Features are: simple structure, stable operation.

Description

technical field [0001] This invention relates to a switch operated by a change of physical state, and more particularly to a mechanical tipping switch. Background technique [0002] For movable gas appliances, if they are placed unreasonably, when they are used at a certain angle, it will affect the normal working conditions of the gas appliances, resulting in unstable combustion, increasing the carbon monoxide content in the combustion exhaust gas, and other abnormal working conditions. cause safety accidents. In order to prevent such adverse phenomena caused by tilting gas appliances, some gas appliances are equipped with anti-dumping switches. When the gas appliances are tilted to a certain angle, the gas valves are controlled to close to protect the gas appliances. At present, most of these switches use mercury switches, which are expensive and extremely unsafe. Mercury can easily cause environmental pollution and make operators prone to mercury poisoning. A large numbe...

In addition, the tilting transmitter disclosed in Chinese patent application No. 98117787.5, and the sensing device disclosed in Chinese patent application No. 01142166.5, which has no installation direction restriction and can reset automatically, all belong to mechanical control switches, and they are all installed in the equipment. There are multiple contacts, which are still in contact with other contacts when the equipment is tilted to conduct electricity or send out electrical signals. They have complex structures, are not easy to process and manufacture, and have high costs. The structures are not suitable for the safety control of gas cookers.
