Embodiment Construction

[0016] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0017] Please refer to Figure 1-2 , the vehicle warning light switch includes a lower housing 1, an upper housing 2, a slider 3, a light guide 4, a button 5, a sliding shrapnel 6, a heart-shaped cam 7, a cam thimble 8, a terminal 9 and a return spring 10. Wherein, the lower housing 1 is embedded in the upper housing 2, thereby reducing the possibility of water immersion inside the automobile switch due to capillary phenomenon. The slider 3 is disposed inside the upper casing 2 so as to slide up and down. The light guide 4 is connected to the upper end of the slider 3. In this specific embodiment, the light guide 4 is sleeved on the outside of the upper end of the slider 3, so that the gap between the light guide 4 and the slider 3 is There is no gap communicating with the outside, so that the possibility of dust intru...

Abstract

The invention discloses a warning lamp switch for a vehicle. The warning lamp switch for the vehicle comprises a lower shell and an upper shell which are mutually matched with each other, a sliding block which can slide up and down is arranged inside the upper shell, the upper end of the sliding block is connected with a light guide body, a terminal is fixed inside the lower shell, a sliding leaf spring is arranged at the inner side of the sliding block in a clamping manner, a movable heart-shaped cam is arranged between the outer side of the sliding block and the inner side of the upper shell, the heart-shaped cam is laterally connected with a cam ejector pin, and the cam ejector pin penetrates through the sliding block and pushes the sliding leaf spring. By adopting the warning lamp switch for the vehicle, the pressure of the cam ejector pin is stable, and the duration of the heart-shaped cam is improved.

Description

technical field [0001] The invention relates to a car switch, in particular to a car warning light switch. Background technique [0002] Existing warning lamp switch is made up of lower housing, upper housing, slide block, light guide body, terminal, heart-shaped cam, cam thimble and return spring. Wherein, the upper case and the lower case are fitted with each other in a manner of stacking up and down; the slider is set in the upper case, and a return spring is arranged between the slider and the lower case, and the light guide is placed in the slider; the terminal It is fixed in the lower casing; a heart-shaped cam is arranged between the upper casing and the slider, and a cam thimble is connected to the heart-shaped cam. [0003] By sliding the slider up and down, the car switch can be turned on and off, thereby controlling the off and on of the brake light. Because the structure of the heart-shaped cam to the cam thimble of the existing warning light switch is too comp...
