Abstract

The invention relates to a switch for an automobile brake lamp. The switch comprises a shell, a shell cover, a pushing rod, a positive electrode pin and a negative electrode pin, wherein the shell and the shell cover are correspondingly matched; one end of the positive electrode pin and one end of the negative electrode pin are respectively connected with electrodes; one end of the pushing rod extends out of the pushing rod hole of the shell, and the other end of the pushing rod is a U-shaped end, and two sides in the U-shaped end are respectively provided with a magnetic block; the two ends of the U-shaped rod of the pushing rod are respectively connected with a spring, and the other end of each spring is connected with the inner side of the shell cover; the positive electrode pin and the negative electrode pin are respectively arranged on the shell cover, and the electrode ends of the positive electrode pin and the negative electrode pin are respectively positioned in the shell cover, wherein one pin is of an L shape, thus the contact points of the electrodes of the positive electrode pin and the negative electrode pin are corresponding up and down, contact point ends of the positive electrode pin and the negative electrode pin are respectively positioned in a seal protection body, and the seal protection body is corresponding to the middle part of the U-shaped end of the pushing rod. The contact points of the switch provided by the invention are isolated from atmosphere, contact oxidation invalidity is avoided, and the service life of the switch is prolonged so as to meet the automobile using requirements; and the switch is suitable for various different automobiles.

Description

technical field [0001] The invention belongs to the technical field of automobile electric appliances, and in particular relates to a switch of an automobile brake light. Background technique [0002] In engineering practice, such as vehicle engineering, construction machinery, industrial equipment, etc., the brake light switch plays a very important role. The switch of the automobile brake light is installed on the brake pedal, and the brake light is switched on by pedal operation to warn the vehicles and pedestrians behind to ensure driving safety. When the vehicle is running, when the driver depresses the brake pedal, the switch push rod moves to the contact joint under the action of the spring, the circuit is connected, and the brake light is turned on. However, in actual use, due to the need for braking operations, the switch needs to be continuously turned on and off. Under the joint action of the internal instantaneous current and the external environment, the switch...
