Abstract

The invention discloses an air pressure signal lamp switch. The switch comprises a switch body, wherein a briquette is arranged in the cavity of the switch body; an electrode seat is arranged above the briquette, and a gasket is arranged between the briquette and the electrode seat; two L-shaped electrodes are arranged in the cavity of the electrode seat, horizontal ends of the two electrodes are connected into a whole, vertical ends of the two electrodes are arranged in the electrode seat in a sliding way and penetrate through the electrode seat; a cloth clamp membrane is arranged under the briquette; a top block is arranged in the briquette in a sliding way; an arc face at the lower end of the top block is supported against the cloth clamp membrane; the upper end of the top block and the horizontal ends of the electrodes are connected into a whole; a seal ring is arranged in the opening of the lower part of the cavity of the switch body; and a through cavity is formed in the center of the seal ring. The air pressure signal lamp switch has a simple structure and is easy to realize, and the air tightness of the air pressure signal lamp switch is improved, thus a signal lamp can be quickly lightened, the automatic reset of the air pressure signal lamp switch is realized, and the safety of the air pressure signal lamp switch is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an air pressure signal light switch. Background technique [0002] When the car is driving, it is necessary to detect the air pressure of the air brake system of the car in real time, and give an alarm in the form of sound and light when the air pressure reaches the set value. The air pressure signal light switch is a kind of air pressure switch, and its function is to turn on the signal light circuit to realize the lighting of the signal light when the air pressure reaches the set value. In the prior art, the alarm of the switch of the air pressure signal light has a delay, the sensitivity is poor, and the switch is likely to fail due to insufficient air tightness. Contents of the invention [0003] The object of the present invention is to provide a switch for an air pressure signal lamp to solve the problems of poor sensitivity and easy failure of the air pressure signal lamp ...
