Isolation type button

Abstract

The invention relates to an isolation type key which contains a button seat, a button lever shaft fixed clamping buckle, a buckle cover, a button spring, a button lever and an electronic control unit, wherein one end of the button lever is placed inside the button seat, and a permanent magnet is embedded inside the other end of the button lever. A magneto sensor is arranged on the electronic control unit, and the mechanical principle is used to enable the magneto sensor state of the electronic control unit to be changed, so that the electronic control unit is informed of carrying out corresponding operations. A button is not directly connected with the electronic unit in an electrical mode, so that the phenomena such as button failure caused by removing water vapor are avoided.

Description

technical field [0001] The invention relates to a button, in particular to an isolated button. Background technique [0002] Generally, electronic products and instrumentation products are equipped with buttons, and ordinary buttons are directly electrically connected to the electronic units of electronic products and instrumentation products. If the buttons installed outside the electronic products are in contact with water vapor, the water vapor is likely to Penetration into the internal electronic unit will cause the keys to fail, and even affect the normal use of electronic products. The electronic control units of the keys and electronic products are electrically connected, and the keys and electronic products can also be damaged when encountering high voltage, high current impact or malicious damage. . [0003] The invention provides an isolated key, which is isolated from an electronic control unit and not directly connected electrically, thereby avoiding the disadv...

AI Technical Summary

Problems solved by technology

[0002]General electronic products and instrumentation products are equipped with buttons, and ordinary buttons are directly electrically connected to the electronic units of electronic products and instrumentation products. If the buttons installed on the outside of the electronic product are exposed to water vapor, the water vapor is likely to seep into the internal electronic unit and cause the button to malfunction, and even affect the normal use of the electronic product. The button and the electronic control unit of the electronic product are electrically connected. , high current shock or malicious destruction, can also damage keys and electronic products

[0003] The present invention provides an isolated button, the button is isolated from the electronic control unit, and is not directly connected electrically, thereby preventing the button part from affecting the use of the button due to contact with water vapor disadvantages
