Air whistle button

Abstract

The invention relates to an air whistle button, which comprises a shell, an electricity connecting component and a pressing component, wherein the first conducting strip of the electricity connectingcomponent is clamped in the first spacing slot of a shell; the first conducting strip is provided with a first stationary contact, and a second conducting strip is provided with a second stationary contact and is clamped in the second spacing slot of the shell; a third conducting strip is independently provided with a first movable contact and a second movable contact, and is positioned between the first stationary contact and the second stationary contact; and one end of the ejection rod of the pressing component penetrates out of the shell to be connected with a button cap, the other end ofthe ejection rod extends into the shell to be connected with the third conducting strip, an elastic restoring element is sheathed to the ejection rod, and the top end of the elastic restoring elementis connected with the button cap. By use of the air whistle button, a phenomenon of contact deflection since a butt joint position is pressed for a long time can be effectively avoided, the button capis unlikely to be broken by pressing, and service life is prolonged.

Description

technical field [0001] The invention relates to a bagpipe button. Background technique [0002] The bagpipe button is a master device for controlling the bagpipe electronic control valve. When the bagpipe button is pressed, the electric control valve is energized, the wind pipe connected to the bagpipe is opened, and when the wind reaches the bagpipe, the bagpipe will whistle. [0003] However, the conventional bagpipe button needs fingers to press the button cap all the time when it sounds, and the button cap is prone to breakage (a hole appears in the button cap) after being pressed for a long time. In addition, the normally open static contact and the normally closed static contact of the bagpipe button are composed of two copper sheets and two contacts respectively. Because the size of the copper sheet is usually small, after long-term contact, the static contact and the moving contact If it cannot be connected well, the two contacts will deviate or even fail to connect...

Problems solved by technology

[0003] However, when the conventional bagpipe button sounds, the finger needs to press the button cap all the time. After pressing the button cap for a long time, it is easy to break (a hole appears in the button cap)

In addition, the normally open static contact and the normally closed static contact of the bagpipe button are composed of two copper sheets and two contacts respectively. Because the size of the copper sheet is usually small, after long-term contact, the static contact and the moving contact It cannot be well connected, and then the two contacts deviate or even fail to connect, resulting in the failure of the bagpipe button
