Embodiment Construction
[0018] Examples such as Figures 1 to 5 As shown, an automobile brake light switch structure, the brake light switch structure is formed by the shell 1, the base 15 and the upper cover 2, and the upper cover 2 is also fixedly provided with an injection molded insert screw 3. The first static contact piece 5 and the second static contact piece 6 are clamped on the shell 1, and the first static contact piece 5 and the second static contact piece 6 are both provided with a contact surface perpendicular to the shell wall of the shell 1. The contact surface of the first static contact piece 5 is higher than the contact surface of the second static contact piece 6 , and a silver contact 8 is riveted on the contact surface of the first static contact piece 5 . The base 15 is provided with a support rod 16 , the base 15 is provided with a contact spring 18 , and the support rod 16 is located in the contact spring 18 . A movable contact 7 is placed above the contact spring 18, and the...

The invention discloses an automobile brake lamp switch structure, which comprises an outer shell, wherein a first static contact piece and a second static contact piece are arranged on the outer shell, and the first static contact piece and the second static contact piece are each provided with a contact surface vertical to the shell wall of the outer shell; a moving contact matched with the first static contact piece and the second static contact piece is arranged in the outer shell, a moving contact spring is arranged under the moving contact, the moving contact spring presses the moving contact tightly so that two ends of the moving contact are in contact and conducted with the contact surfaces of the first static contact piece and the second static contact piece, and an ejection rod is arranged on the moving contact; and the contact surface of the first static contact piece is positioned higher than that of the second static contact piece, and a silver contact is arranged on the contact surface of the first static contact piece. The automobile brake lamp switch structure can effectively reduce arc through the contact structural position and the conduction relation, prevents the contact pieces from erosion, prolongs the service life of a brake lamp switch, is convenient and simple in installation method, and can be widely used in the field of automobile brake lamp switches.
Description
technical field [0001] The invention relates to the field of automobile switches, in particular to an automobile brake light switch structure. Background technique [0002] The car brake light switch is used frequently, so it is required to have a longer service life than other car switches. The traditional brake light switch has been ablated due to the lack of protective measures for the contacts, and can only reach the service life of the general switch. In addition, the traditional brake light switch push rod is in direct contact with the moving contact piece. During the movement of the contact piece, it is greatly affected by the external push rod, and the distance from the contact piece to the top of the push rod is relatively long, so the slight deflection of the top of the push rod , There will be a large positional deviation of the contact piece, so that the moving contact piece and the static contact piece cannot be effectively and smoothly contacted, the contact a...
