Embodiment 1
[0013] Embodiment 1: a motor drive circuit, used to drive the motor to run, and realize the functions of neutral gear and two-speed speed of the motor. The motor drive circuit includes such as figure 1 The main control circuit board shown is provided with a slide switch for adjusting the gear position of the motor on the main control circuit board. The slide switch includes a slide key for sliding operation and a switch circuit board that cooperates with the slide key to complete gear conversion, such as figure 2 shown. Specifically, there is a first contact group composed of four contact connections on the sliding key, and a second contact group that can be in contact with the first contact group is included on the switch circuit board. When the sliding key slides to different When in the position, it corresponds to different gear positions and contacts with different contacts in the second contact group.
[0014] as attached image 3 As shown, the second contact group i...

The invention relates to a sliding switch. The sliding switch comprises a sliding key provided with a first contact group and a switch circuit board, wherein the switch circuit board comprises a second contact group and a line, the second contact group comprises a contact 0 of which the length direction is in the sliding direction of the sliding key, and a plurality of pairs of stationary contacts which are distributed in the length direction of the number contact 0; the stationary contacts are divided into two groups, one group of the stationary contacts successively comprises a first neutral position contact pair corresponding to a neutral position, and a power supply contact pair corresponding to a plurality of gear positions, from front to tail in the length direction of the contact 0, the other group of the stationary contacts successively comprises a second neutral position contact pair corresponding to the neutral position, and a working contact pair corresponding to a plurality of gear positions, from front to tail in the length direction of the contact 0, the working contact pair comprises an idled contact piece and a control contact piece, the adjacent idled contact piece and the adjacent control contact are connected in the sliding direction of the sliding key through a bare connecting line. According to the sliding switch disclosed by the invention, the distribution of contacts is reasonable, and gear switching can be conveniently and continuously performed.
Description
technical field [0001] The invention relates to a sliding switch for shifting gear positions. Background technique [0002] Slide switches are a new type of switch group that accompanies the emergence of printed circuit boards (PCBs). Today, when transistors and integrated circuits are widely used, the application of PCB as the basis of circuits has broad and long-term prospects, so the vitality of slide switches is very long. However, in the circuit board used in the existing sliding switch, the structural design of the contacts corresponding to each different gear position is relatively unreasonable, making it impossible to conveniently realize the sliding gear switching. Contents of the invention [0003] The purpose of the present invention is to provide a sliding switch device which improves the layout of the contacts on the switch circuit board, so that the gear position can be adjusted conveniently through the sliding of the sliding switch. [0004] In order to ac...
