Description

Technical Field

[0001] The utility model relates to the technical field of detection switches, in particular to a patch micro detection switch. Background Art

[0002] The patch micro detection switch is an electronic component that connects the circuit by pressing and rebounding to play a protective role. However, the conventional button-type switch contact structure with a tube spring has a large spring travel range, and the contact and rebound response speed is not fast enough, resulting in insufficient switch contact sensitivity and unable to meet the use requirements of the detection switch. Therefore, we propose a patch micro detection switch. Utility Model Content

[0003] The utility model proposes a patch micro detection switch, which solves the problem that the conventional button-type switch contact structure with a tube spring has a large spring travel range and insufficient contact and rebound response speed, resulting in insufficient switch contact sensitivity and failure to meet the use requirements of the detection switch.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A patch micro detection switch comprises a rubber seat, a cover plate, a pressure handle, and a contact spring. Terminals are injection-molded on both sides of the bottom of the rubber seat, and a cover plate is arranged above the rubber seat and locked by a snap-fit ​​structure. A contact spring is installed inside the rubber seat, and a synchronously rotating pressure handle is arranged on one side of the contact spring, and the pressure handle extends upward through the rubber seat to the outside thereof.

[0006] As a further preferred solution of the utility model, a through pressing groove is opened inside the cover plate, and the pressing handle passes through the pressing groove and extends upward.

[0007] As a further preferred embodiment of the present invention, a group of symmetrically distributed buckles are provided on both sides of the cover plate.

[0008] As a further preferred solution of the utility model, card slots are provided at the positions of the buckles on both sides of the rubber seat, and card blocks are provided inside the card slots, and the buckles are matched with the card blocks for fixed connection.

[0009] As a further preferred solution of the utility model, the center of the contact spring and the pressure handle are installed inside the rubber seat through a rotating shaft to form a synchronous rotation structure.

[0010] As a further preferred solution of the utility model, the terminals include terminal A, terminal B, terminal C, and terminal D, which are distributed at the four corners of the rubber base.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the terminals of the patch micro detection switch of the utility model are combined with the rubber seat by injection molding, the spring-type contact structure has sensitive and reliable contact, the contact terminal is turned on by pressing down the contact spring, and is disconnected by releasing the spring rebound, and the response speed of the contact spring is faster, which can meet the high-sensitivity detection requirements.
