Problems solved by technology

[0003] Although there are hermetically sealed electrical switch assemblies today, which can achieve waterproof, anti-corrosion, dust-proof, and explosion-proof functions by sealing internal components and circuits, most of them have complex structure principles, large volumes, and high prices. Patent structures such as U.S. No. 4,739,291 and No. 5,777,536 have been invented to provide a small-volume, low-cost sealed electrical switch assembly. However, its internal structure is difficult to call simplification, and the production cost in practical production needs to be further reduced.

Embodiment Construction

[0026] Please see first Figure 1 to Figure 4 , the enclosed electrical switch assembly 100 provided by the first preferred embodiment of the present invention includes:

[0027] A housing 110 and a cover 112 covering the opening on the top surface of the housing 110 are both made of non-paramagnetism materials (such as plastic steel, stainless steel, aluminum alloy, etc.). After the cover 112 is closed, an airtight main chamber 114 is formed in the center of the casing. In this embodiment, the two ends of the casing (corresponding to the two opposite sides of the main chamber 114) are each provided with a wiring chamber 116 with an opening facing upwards, and a plurality of wiring terminals 118 are respectively provided on the two outer surfaces of the two wiring chambers 116. For plugging of external wires. The center of the cover 112 is embedded with two long-shaped magnetically conductive parts 120 made of magnetically conductive materials (such as pure iron, nickel-iron...

Abstract

An assembly of sealed electric switch with the water proof and antidusk functions includes mainly a shell, a sealed container to contain the entire electric switch device and some conductive wires toconnect the connecting terminals of electric switch device with the outside power line in non-interference of sealing ability to the container. The first magnetic stress device is set up in the container and it is clutched mutually with the driving lever of the electric switch device for linked action to each other as well as the second magnetic stress device is set up correspondingly at shell outer to make magnetic force attracting to each other with the first magnetic stress device for synchronous linked action to each other.

Description

technical field [0001] The invention relates to an electric switch, in particular to a sealed electric switch assembly with waterproof, anti-corrosion, dust-proof and explosion-proof functions and low manufacturing cost. Background technique [0002] Because the casing of general electrical switches does not have the sealing effect, the metal terminals in them are easy to be gradually corroded or covered with dust due to moisture and dust in the air, resulting in reduced sensitivity of the switch or malfunction, and even, sometimes may cause a short circuit And cause a fire accident. In addition, it is often used as a main switch and can automatically cut off the circuit breaker when the load side is overloaded. Since the internal components and circuits are not isolated from the outside world, if flammable substances such as oil stains accumulate near the switch, or At that time, the air was filled with flammable and explosive gases, and the sparks generated when opening a...
