Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative pur...

Abstract

The invention discloses a microswitch, comprising a bottom shell, a contact terminal and a pressing member. The contact terminal comprises a conductive sheet and a terminal. The conductive sheet is arranged on the bottom shell. The terminal comprises a bottom sheet and a contact convex ring. The pressing member comprises a button and a spring piece, wherein the spring piece is in contact with thebutton; the conductive piece is used for holding the spring piece; when the button is pressed, the conductive piece is used for squeezing the spring piece to deform and making the deformed part of thespring piece come into ring contact with the contact convex ring; when the button is pressed, the conductive piece is used for pressing the spring piece to deform. A microswitch By setting the contact convex ring on the backsheet, the good contact between the spring and the terminal can be ensured, and the contact pressure can be increased with the smallest contact surface, thus maintaining the continuity of the whole micro-switch in the movement process, finally realizing the conduction function of the micro-switch, and ensuring that the micro-switch can output stable waveform.

Description

Technical field [0001] The invention relates to the field of micro switches, in particular to a micro switch. Background technique [0002] A micro switch is a contact mechanism that has a small contact interval and a snap-action mechanism, and uses a specified stroke and a specified force to switch action. It is covered by a shell and has a drive rod outside of it. Because the contact distance of the switch is relatively compared Small, hence the name micro switch, also called sensitive switch. Also known as sensitive switch, snap action switch. A quick switch actuated by pressure. Used for door switches in anti-theft systems, etc. The micro switch, as the name suggests, uses a very small force to switch. It is a switch in which external mechanical force acts on the moving reed through a transmission element, so that the fixed contact at the end and the moving contact are quickly connected or disconnected. The micro switch has a small contact interval and a snap-action mech...
