Description

Technical Field

[0001] The utility model relates to the technical field of encoder design, in particular to a switch encoder. Background Art

[0002] A rotary switch encoder is an encoder product that generates regular pulses by means of signals and the regular rotation or movement of parts to form contact points. By coordinating with an IC, it can perform functions such as incrementing, decrementing, and page turning. Examples include mouse page turning, menu selection, audio volume adjustment, frequency control, oven temperature control, and frequency control for medical devices.

[0003] However, in existing switch encoders, the ground terminal of the switch is generally shared with the common terminal of the encoder, which cannot meet the customer's requirements for non-sharing. At the same time, the brush claws in the brush are mostly double-claw or multi-claw structures, which are difficult to process and easily damaged in actual use, greatly reducing the user experience.

[0004] Therefore, it is necessary to propose a technical means to solve the above defects. Utility Model Content

[0020] Specifically, in this embodiment, during operation, the brush 30 is driven to rotate by externally rotating the rotating shaft 50, which in turn drives the brush 30 through the undulating disk 40, causing the brush 30 to move relative to the brush 20, allowing the brush 20 to transmit a signal through the pulsation output pin 70. By pressing the rotating shaft 50, the key spring 60 contacts the metal contact 90, thereby enabling the encoder to function as a switch. By providing the pulsation output pin 70 and the power output pin 80 on either side of the mounting base 10, the requirement for the client to not share pins is met, thereby improving user convenience.
