Example Embodiment

[0016] Such as Figure 4-Figure 6-2 As shown, the key switch of the present invention includes a base 2, a metal foot 1 is provided on the base 2, a spring 3 is provided in the base 2, and a push shaft 5 is sheathed on the spring 3, and a contact piece is provided on the push shaft 5 4. There are 4 metal feet 1 on the base 2 and they are respectively arranged at 4 corners, which are symmetrically distributed. The upper side plate of the base 2 is provided with a slot in the middle to divide the side plate into two halves. The contact piece 4 (power-on piece) is a conjoined integral structure. Adopting 4-pin symmetrical design, no direction recognition is required during installation, which improves work efficiency. At the same time, combined with actual needs, the principle of energization is simplified, and the frequency of errors due to circuit gear conversion is reduced, which is more practical. The new slotted structure of the base can completely eliminate the hidden dang...

Abstract

The invention discloses a key switch which comprises a base. Four metal pins are arranged on the base, springs are arranged in the base, push shafts sleeve the springs, contact pieces are arranged on the push shafts, and the four metal pins on the base are respectively arranged at four corners and are symmetrically distributed. The key switch has the advantages that the four pins are symmetrical with one another, accordingly, directions do not need to be identified when the key switch is used and mounted, and the work efficiency can be improved; the key switch is combined with actual requirements, an energization principle is simplified, accordingly, error frequencies due to circuit tap position switching can be reduced, and the key switch is high in practicality; the base is additionally provided with grooved structures, and accordingly 'shoot-through' potential hazards between terminals can be fundamentally completely eliminated.

Description

technical field [0001] The invention relates to a switch, in particular to a key switch. Background technique [0002] Such as Figure 1-Figure 3 as shown, figure 2 and image 3 The traditional key switch in China needs to switch between power-on gears and must carry out direction recognition, which has potential safety hazards of reverse circuit. image 3 In normal state: 1 and 2 are turned on, 4 and 5 are turned on, and at the same time, figure 1 The middle shrapnel (contact piece 4) has a split structure, and there is a potential safety hazard that some of the pins are deformed and affect the poor power supply of the whole product. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a novel key switch. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] Key switch, including a base, with metal feet on the base, a spring inside the base, and a push shaf...
