Description

Technical Field

[0001] The utility model relates to a three-position push button switch structure. Background Art

[0002] A three-position switch is a switch with three different working states. Generally, these three states are open, closed, and intermediate. Different three-position switches may look different, but their structures are basically the same. They are basically composed of switch mechanisms, control circuits, contacts, etc. The existing three-position push button switch has a complex structure and cannot be quickly assembled. If the switch is missing, it cannot be discovered in time, which affects the subsequent use. Utility Model Content

[0003] The purpose of the utility model is to provide a three-position push button switch structure to solve the above technical problems.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A three-position button switch structure comprises a position button, a position button main shell, a position button compression spring, a limit buckle compression spring, a fixed contact, a button holder, a limit bracket and a moving contact. The position button is connected to the position button main shell, and the position button can move up and down. Position button compression springs are arranged on both sides of the position button main shell, and the position button compression spring can realize the rise of the position button. A button holder is arranged below the position button main shell, a limit bracket is arranged above the button holder, a limit buckle compression spring is installed on the limit bracket, a limit buckle is installed opposite to the limit buckle compression spring, an integrally formed moving contact is arranged below the limit bracket, the button holder is of a recessed design, the limit bracket can move downward in the button holder, a fixed contact is arranged above the button holder, the fixed contact is located below the moving contact, and a warning spring is arranged below the button holder.

[0006] Preferably, the warning spring is of pagoda-like design, the warning spring is located below the clamp, the clamp is connected to the button socket, and the warning spring is coated with yellow fluorescent powder.

[0007] Preferably, the position button rises under the action of the position button compression spring to separate the moving contact from the fixed contact, and the position button is manually compressed, the position button moves downward, thereby driving the limit bracket to move downward so that the moving contact and the fixed contact contact, and the position button is compressed again, the limit bracket continues to move downward, so that the fixed contact is deformed and moved downward, thereby separating the moving contact from the fixed contact.

[0008] Compared with the prior art, the utility model has the following advantages: the utility model has a reasonable design; the step-type design of the position button and the limit bracket facilitates the quick assembly of the switch, the assembly is simple, and the modularization degree is high; the warning spring is located under the button holder. If the switch is missing, the pagoda-shaped warning spring will pop up to remind people to replace it in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-4 As shown, a three-position push button switch structure includes a position button 1, a position button main shell 2, a position button compression spring 3, a limit buckle compression spring 4, a fixed contact 5, a button holder 6, a limit bracket 7, and a moving contact 8. The position button 1 is connected to the position button main shell 2, and the position button 1 can move up and down. Position button compression springs 3 are provided on both sides of the position button main shell 2, and the position button compression spring 3 can realize the rise of the position button 1. A button holder 6 is provided below the position button main shell 2, and a limit bracket 7 is provided above the button holder 6. A limit buckle compression spring 4 is installed on the limit bracket 7, and a limit buckle 9 is installed opposite to the limit buckle compression spring 4. An integrally formed moving contact 8 is provided below the limit bracket 7, and the button holder 6 is a recessed type According to the design, the limit bracket 7 can move downward in the button holder 6, and a fixed contact 5 is provided above the button holder 6, and the fixed contact 5 is located below the moving contact 8. A warning spring 11 is provided below the button holder 6, and the warning spring 11 is of a pagoda-style design. The warning spring 11 is located below the clamp 10, and the clamp 10 is connected to the button holder 6. The warning spring 11 is coated with yellow fluorescent powder. The position button 1 rises under the action of the position button compression spring 3, so that the moving contact 8 is separated from the fixed contact 5. The position button 1 is manually compressed, and the position button 1 moves downward, thereby driving the limit bracket 7 to move downward so that the moving contact 8 contacts the fixed contact 5, and then compressing the position button 1, the limit bracket 7 continues to move downward, so that the fixed contact 5 is deformed and moved downward, so that the moving contact 8 is separated from the fixed contact 5, and the three-control switch is in the disconnected state.

[0015] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
