Problems solved by technology

[0002] The aviation switch is characterized by low cost and wide application. The existing contact switch conducts electricity through the parts that cooperate with each other, so there is a phenomenon of poor contact during ignition.
In addition, poor plating or corrosion of any of these parts will cause poor electrical conductivity; and due to the gap fit of the parts, the conduction current here is unstable, and the conductive resistance will be relatively large

Abstract

The invention discloses an aviation switch. The aviation switch comprises a valve seat (5) and a valve body (1), wherein the valve seat (5) and the valve body (1) are mutually buckled into a whole body to form a contact piece switch casing; the valve seat (5) and the valve body (1) are provided with a fixed contact piece (3) in a clamping way; a torsion bar (7) is movably inserted into the contact piece switch casing, with one end penetrating through the valve seat (5); a moving contact piece (4) is mounted on the torsion bar (7); a plurality of raised contacts (31) are distributed on one surface, opposite to the moving contact piece (4), of the fixed contact piece (3). The aviation switch has the characteristics of being more stable in electrical conduction and low in conduction resistance.

Description

Technical field: [0001] The invention relates to the technical field of switches, and more specifically relates to an aviation switch. Background technique: [0002] The aviation switch is characterized by low cost and wide application. The existing contact switch conducts electricity through the parts that cooperate with each other, so there is a phenomenon of poor contact during ignition. In addition, poor plating or corrosion of any of these parts will cause poor electrical conductivity; and due to the clearance fit of the parts, the conduction current here is unstable, and the conductive resistance will be relatively large. Invention content: [0003] The purpose of the present invention is to provide an aviation switch, which has the characteristics of more stable electric conduction and small conduction resistance. [0004] In order to achieve the above object, an aviation switch of the present invention includes a valve seat and a valve body, the valve seat and the...
