Universal falling protection switch improved structure

Abstract

The invention discloses a universal falling protection switch improved structure. The structure comprises a flange seat, a reed switch is arranged at the centre of an upper end face of the flange seat, the reed switch is electrically connected with an external control circuit, a shell buckled above the flange seat is arranged on the flange seat, a flexible silk thread is hung on an inner roof of the shell, the extension line of the flexible silk thread vertically penetrate the centre of the reed switch in a normal state, and a permanent magnet is hung at a lower end of the flexible silk thread. By using a proven reed switch with built-in neon, the universal falling protection switch improved structure is good in sealing performance, strong in magnetic induction receiving ability, good in conducting performance and pollution-free, and cannot be corrode by the environment; and a falling switch with very small volume can be manufactured for more demand.

Description

technical field [0001] The invention relates to a circuit control switch, in particular to an anti-tilt switch used for gas appliances and electric appliances. Background technique [0002] At present, there are generally two types of anti-dumping switches for gas appliances and electrical appliances used in the market: micro switch type and mercury type. The micro switch type is because the two contact pieces rely on the vertical swing of gravity to press down the pressure plate, so that the micro switch Work, because the spring force of the micro switch must be large to meet the good contact of the contact piece, although some surfaces are silver-plated, but due to long-term work, the surface coating of the contact piece will be damaged, thereby oxidized, and the contact effect is not good. The shape is also larger. The mercury switch makes the two inserts contact by the rolling of the mercury ball, and the effect is very good, but because the mercury is highly toxic, it ...

[0002] At present, there are generally two types of anti-dumping switches for gas appliances and electrical appliances used in the market: micro switch type and mercury type. The micro switch type is because the two contact pieces rely on the vertical swing of gravity to press down the pressure plate, so that the micro switch Work, because the spring force of the micro switch must be large to meet the good contact of the contact piece, although some surfaces are silver-plated, but due to long-term work, the surface coating of the contact piece will be damaged, thereby oxidized, and the contact effect is not good. The shape is also larger

The mercury switch relies on the rolling of the mercury ball to make the two inserts contact, and the effect is very good. However, due to the strong toxicity of mercury, it will seriously pollute the environment. At present, many countries have begun to stop using it.
