Problems solved by technology
[0003] The purpose of the present invention is to provide a combination switch with a retarder function, which solves the problem that the retarder braking function on the existing automobile combination switch is relatively simple, and often can only be designed due to space and structure constraints. The retarder function of one or two gears, and the problem that the service life is also low

The invention discloses a combined switch with the retarder function. The combined switch comprises a shell, a socket, and an upper cover. A switch handle is arranged at one side of the shell; a copper insert is arranged on the socket; a retarder sliding block assembly is arranged on the socket; one group of first movable contact pieces is arranged at the back of the retarder sliding block assembly; and the switch handle is provided with a handle assembly. A first rotation shaft is arranged in the shell; and a first shaft hole is formed in the back of the handle assembly. A support plate is arranged above the retarder sliding block assembly; and a buffer transmission mechanism is arranged above the support plate. A first gear compression spring is arranged on the handle assembly; a first gear pin roller is arranged on the top of the first gear compression spring; and a gear track slot is formed in the back the upper cover. Therefore, problems that the retarder brake function of the existing automotive combined switch is single and only one-gear or two-gear retarder function is designed because of spatial and structural restrictions, and the service life is short are solved.
Description
technical field [0001] The invention relates to a combination switch with retarder function. Background technique [0002] As one of the auxiliary safety configurations commonly used in medium and heavy vehicles, the retarder function is very important for the auxiliary braking effect during the driving process of the vehicle. The retarder braking function on the traditional automobile combination switch is relatively simple, and often only one or two retarder functions can be designed due to space and structural constraints, and the service life is also relatively low (usually 50,000 times). With the improvement of customers' demands on driving comfort, safety and service life, the combination switch with multi-gear and higher reliability retarder function has become a development demand. Contents of the invention [0003] The purpose of the present invention is to provide a combination switch with a retarder function, which solves the problem that the retarder braking ...
