The utility model provides a traffic police contact whistle. A pneumatic switch is fixed in a whistle neck and is formed by a right contact, a left contact, a spring and a copper piece. A sound box is fixed at the lower part of the whistle and is internally equipped with an alarm and batteries. The panel upper left corner of the sound box is equipped with a switch, and the panel lower part of the sound box is equipped with buttons. The anode ends of the batteries are electrically connected to the anode end of the alarm, and the cathode ends of the batteries are electrically connected to one end of the switch. The other end of the switch is electrically connected to the left contact and one end of each of the buttons. The cathode end of the alarm is electrically connected to the right contact and the other end of each of the buttons. The alarm is an AQB-110 mini alarm and can emit strong whistle sound. A user can blow the traffic police contact whistle gently, the pneumatic switch in the whistle immediately starts to act, the right contact and the left contact are pressed by the copper piece and are in conduction, the alarm emits the strong whistle sound to substitute the whistle sound generated by blowing a whistle strongly, the sense is real, the labor of the traffic police is saved, the traffic police is not very tired, and the thirst of the traffic police is avoided.
Description
1.
