Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a rocker switch with improved service life. Background Technology

[0002] A rocker switch, also known as a rocker switch, is a small, high-capacity power switch suitable for household appliances and office equipment. Rocker switches are commonly used in devices such as water dispensers, treadmills, computer speakers, electric bicycles, and televisions.

[0003] Currently, rocker switches on the market typically consist of a switch housing and a rocker button mounted on the housing. However, there is a significant gap between the rocker button and the switch housing, which allows water to seep in during use, causing internal short circuits and affecting the switch's functionality. Therefore, the applicant has developed a useful design to solve this problem, and the technical solution described below arose from this context. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the traditional rocker switch design and provide a product with good sealing performance.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A rocker switch with improved service life includes a housing and a button pivotally disposed therein. The housing has a sealing partition and forms a first chamber and a second chamber. The button has a fixed cylinder that passes through the sealing partition. The sealing partition has a sealing bushing. The sealing bushing has a sealing sleeve that is tightly fitted onto the outer wall of the fixed cylinder. The sealing sleeve moves with the fixed cylinder. The outer wall of the sealing sleeve has a plurality of equally spaced and elastic pleats from top to bottom.

[0007] Preferably, the corners of the housing are provided with support portions, and adjacent support portions are provided with sealing portions.

[0008] Preferably, the sealing partition is provided with a sealing groove that allows the sealing portion to pass through, and the sealing partition is connected and fixed to the inner wall of the housing by sealant.

[0009] Preferably, the sealing partition has a through hole for the sealing bushing to pass through, and the end face of the through hole has a countersunk hole.

[0010] Preferably, the end face of the sealing bushing is provided with a connecting portion and is fixedly disposed in the countersunk hole.

[0011] Preferably, the second chamber is provided with a first stationary spring foot and a second stationary spring foot. The first stationary spring foot is provided with a stationary contact point, and the second stationary spring foot is provided with a rotatable moving spring plate. The back of the moving spring plate is provided with an arc-shaped contact surface.

[0012] Preferably, the button is located in the first chamber, and the fixed cylinder is provided with a liftable abutment rod. The abutment rod is provided with a spring, which acts on the button so that the abutment rod abuts against the abutment surface.

[0013] Beneficial effects:

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, by setting a sealing partition, divides the interior of the housing into two independent spaces. The first stationary spring foot, the second stationary spring foot, and the moving spring are placed in the highly sealed second chamber. This design protects the spring structure from the intrusion of humid air, water vapor, moisture, and dust. The sealing partition, together with the sealing sleeve, enhances the sealing and protection capabilities of the second chamber, further preventing external moisture from seeping in. This protective measure helps maintain the electrical performance and mechanical stability of the spring structure and extends its service life. In addition, the elastic pleats on the sealing partition can adapt to the relative movement during button rotation, helping to alleviate the sticking phenomenon during button operation and improving the smoothness of operation.
