Rotary push switch

Abstract

The invention relates to a rotary push switch employing a one-touch ON / OFF mode, which is mainly applied to an automobile interior lamp and the like. The invention provides the rotary push switch. In order to ensure the stability of electrical characteristics of the switch, contacts are formed by tension of a mobile terminal; the mobile terminal is integrally inserted into a shaft; a four-contact form is adopted; an electrical pattern is formed by a PCB substrate; and a lubricating oil coating technology when the switch is fabricated is eliminated. The rotary push switch provided by the invention has excellent switch operation feeling, further prolongs the lifetime, prevents the terminal from being separated and deforming, keeps and supports the tension of the terminal and develops excellent contact performance; the electric shock flatness and the pattern position are uniform. A coating of the rotary push switch comprises contact surfaces, so that a very stable electrical function is kept. In addition, two contacts form a unified thick point, so that the electrical property can still be kept even if one contact loses the function. Furthermore, the lubricating oil coating technology when the switch is fabricated is eliminated, so that the procedure is simplified; and mass production is achieved.

Description

technical field [0001] The present invention relates to a rotary type push switch (Rotary type push switch), especially a rotary type push switch mainly used for one-touch ON / OFF type of automotive interior lamps and the like. Background technique [0002] Generally speaking, the rotary push switch is a switch suitable for low-voltage circuits such as automotive circuits, and is mainly used to adjust the work of automotive interior lights such as overhead lights, map lights, or other auxiliary lights. [0003] The above-mentioned switch makes the electric contact part continuously generate the continuous operation of the button of the constraint through the rotary switch device, and makes the circuit work and release sequentially. [0004] For example, the above-mentioned rotary push switch is a switch that will complete the ON / OFF action in sequence if the button is pressed repeatedly. [0005] The above-mentioned rotary push switch includes buttons, springs, solenoids, mo...

AI Technical Summary

Problems solved by technology

[0010] However, in the above-mentioned existing rotary push switch, the contact mode is completed by pressurized contact of the contact protrusion of the movable terminal. The protruding part is easy to wear, resulting in poor contact contact and shortening the life of the switch

[0011] In particular, since the above-mentioned movable terminal is formed in the shape of an integral disc, stable contact cannot be ensured if deformation such as twisting occurs.

[0012] In addition, since the coupling between the above-mentioned shaft and the moving terminal is assembled by insertion, the contact part may come off due to misalignment between the shaft and the moving terminal, and correct contact performance cannot be ensured.

[0013] In addition, in the existing rotary push switch, lubricating oil is applied to the contact part during production, so the process is increased, and the surroundings of the components become messy due to the application of lubricating oil
