Control switch based on the first-order buoyancy principle of magnetic liquid

Abstract

The invention discloses a control switch based on a magnetic liquid first-order buoyancy principle, and belongs to the field of mechanical engineering. The device comprises insulated magnetic liquid,an insulating container, a plurality of conducting balls, static contact pieces, a magnetic field unit and a circuit part, wherein the static contact pieces comprise a left static contact piece and aright static contact piece; and the conducting balls comprise a left conducting ball, a right conducting ball, a middle conducting ball group and a compensating conducting ball group. Through the adoption of the control switch based on the magnetic liquid first-order buoyancy principle, the on and off of the switch are controlled by applying the magnetic field unit, and the wearing capacity of thestatic contact pieces is compensated automatically by the conducting balls through buoyancy, so that the switch-on reliability of the switch is strengthened greatly, and the service life of the switch is prolonged. The control switch based on the magnetic liquid first-order buoyancy principle disclosed by the invention has the advantages of novel structure, convenient control, stable performanceand the like, and a new choice is provided for controlling circuit on-off equipment.

Description

technical field [0001] The present invention relates to circuit control switchgear, more particularly, it relates to a control switch based on the principle of first-order buoyancy of magnetic liquid. Background technique [0002] Traditional switches are mostly composed of mechanical springs, shrapnel and conductive contact materials (copper, silver, etc.), such as the published patents CN204011211U and CN204011194U, etc., all adopt this type of structure. After the switch is pressed for a long time, the elasticity of the spring and shrapnel will decrease, and the contact material will be severely deformed and worn, resulting in difficult reset and poor contact between the dynamic and static contacts, which reduces the reliability of the switch during use, and shortens the service life of the contact switch. In addition, traditional switches are widely used, and the market share is as high as 99%, which causes people's aesthetic fatigue and lacks innovation. [0003] Magne...

Problems solved by technology

After the switch is pressed for a long time, the elasticity of the spring and shrapnel decreases, and the contact material is deformed and worn seriously, resulting in difficult reset and poor contact between the dynamic and static contacts, which reduces the reliability of the switch during use and shortens the service life of the contact switch.

In addition, traditional switches are widely used, and the market share is as high as 99%, which causes people's aesthetic fatigue and lacks innovation.
