Embodiment

[0024] Such as Figure 1-2 As shown, the embodiment of the present invention provides a new key switch, including a fixed bracket 5, a fixed magnet 6 is arranged in the middle and lower part of the fixed bracket 5, a Hall element 2 is arranged on the upper part of the fixed magnet 6, and a sliding sleeve on the outer periphery of the upper part of the fixed bracket 5 There is a key shell 1, and the top of the key shell 1 is inlaid with a moving magnet 4. When the key switch is installed and assembled, the moving magnet 4 is fixedly assembled with the key shell 1. When the key shell 1 is pressed, the key shell 1 can pass Drive the moving magnet 4 to move up and down to realize the cooperative work between the moving magnet 4 and the fixed magnet 6, the fixed bracket 5 is fixedly assembled with the Hall element 2 and the fixed magnet 6 respectively, and the fixed magnet 6 and the Hall element 2 are fixedly arranged on the fixed bracket 5, the fixed setting can meet the requireme...

Abstract

The invention provides a novel key switch, and relates to the technical field of key switches. The novel key switch comprises a fixed support, a fixed magnet is arranged on the lower middle portion in the fixed support, a Hall element is arranged on the upper portion of the fixed magnet, the periphery of the upper portion of the fixed support is sleeved with a key shell in a sliding mode, and a movable magnet is embedded in the top in the key shell. The movable magnet and the key shell are fixedly assembled, the fixed support is fixedly assembled with the Hall element and the fixed magnet, an output pin is outputted through the fixed support, the key shell and the fixed support are in sliding fit, the key shell and the fixed support are limited at the farthest distance, and the movable magnet and the fixed magnet are assembled according to the requirement that like poles repel each other. Through the combination of the movable magnet, the fixed magnet and the Hall element, the service life of the Hall element is long when the Hall element is used, the use precision of the switch is high, the switch induction is sensitive, and the stable output signal and no signal jitter of the output pin are realized.

Description

technical field [0001] The invention relates to the technical field of key switches, in particular to a novel key switch. Background technique [0002] Electronic switches with magnets and Hall elements have been widely used, and their service life is much higher than that of similar mechanical switches and membrane switches. The bistable characteristic of the Hall element completely solves the problem of the bit error rate and signal jitter of the electronic switch that the magnet and the Hall element cooperate with. However, this type of switch is realized by the Hall effect of a single magnet and the Hall element to switch the logic function of the switch. Due to the high magnetic field strength at the magnetic pole of the magnet, this type of switch has a large volume and low precision. [0003] There are roughly the following types of switches on the market: [0004] Mechanical switch: It uses the contact of conductive material to complete the conductive function. Du...
