Abstract
The utility model relates to a light switch, which is composed of an outer case, a slide block, a movable contact, a static contact, a power-supply line, and a decorative panel. The outer case is made of insulation materials. The upper part of the outer case is a rectangular tank, and the lower part of the outer case is a sealed chamber. The movable contact and the static contact are arranged in the sealed chamber. The power-supply line which is connected with the movable contact and the static contact extends out of the outer case. A permanent magnet is arranged on the movable contact. The slide block is arranged in the rectangular tank and is clamped in the decorative panel. One side of the slide block facing the sealed chamber is provided with two permanent magnets with different magnetic properties. The light switch of the utility model solves the problem that a past magnetic switch has complicated structure and big volume. The utility model is especially suitable for working in the flammable or damp environment, and the damp-proof and explosion-proof functions can be effected.
Description
The utility model belongs to a kind of permanent magnet magnetic force switch that is used to throw light on and starts.
A kind of magnetic switch that provides in prior art 91215399 patents also has mechanical component except that having the magnetic force member, its structure more complicated, volume are big, the cost height.
The purpose of this utility model is, designs a kind of simple in structure, illumination magnetic switch that cost is low.
The utility model is made up of shell, slide block, moving contact, fixed contact, power line, decoration panel: shell is made by insulating material, its top is a rectangular channel, the bottom is a sealing chamber, moving contact and fixed contact are arranged in the sealing chamber, the power line that is connected with fixed contact with moving contact stretches out shell, and permanent magnet is housed on the moving contact.Slide block is contained in the rectangular channel and is stuck in the decoration panel, and its one side towards sealing chamber is equipped with two different permanent magnets of magnetic.
The utility model is simple in structure, and parallel moving slider is directly controlled moving contact and moved, make dynamic/static contact close, from, promptly connect or powered-down.
