Encoder combination switch

Abstract

The invention discloses an encoder combination switch which is characterized in that the encoder combination switch comprises an upper cover plate, a middle cover plate and a lower cover plate, a first encoder and a second encoder are arranged between the upper cover plate and the middle cover plate in parallel, a potentiometer is arranged between the middle cover plate and the lower cover plate,and a first control shaft is arranged between the first encoder and the potentiometer, the first control shaft penetrates through the first encoder to be connected with a knob of the potentiometer, asecond control shaft is arranged on the second encoder, a rotating rod is arranged at the upper end of the first control shaft, pawls are arranged at the two ends of the rotating rod, a ratchet wheelis arranged at the upper end of the second control shaft, and a transmission groove allowing the lower end of the first control shaft to be inserted is formed in the knob of the potentiometer. A spring abutting against the first control shaft is arranged in the transmission groove. The encoder combination switch provided by the invention has the characteristics of small occupied space, combinationfunction, simplicity in operation and convenience in circuit connection.

Description

technical field [0001] The invention relates to a combination switch, in particular to an encoder combination switch. Background technique [0002] Encoders and potentiometers are commonly used electronic components in measurement and control instruments. At present, the two electronic components are used separately and connected to each other through wiring. However, in the process of use, especially when the instrument panel of the measurement and control instrument is small or the internal assembly space is insufficient, the disadvantages of the traditional use of encoders and potentiometers are obvious: 1. It takes up a large area of ​​the instrument panel, and both components need to be relatively large 2. The operation function is single, and each knob can only achieve a single function, which often cannot achieve the expected function well; 3. The operation is inconvenient, and the two knobs require multiple operations; 4. The wiring connection is troublesome, and the...

However, in the process of use, especially when the instrument panel of the measurement and control instrument is small or the internal assembly space is insufficient, the disadvantages of the traditional use of encoders and potentiometers are obvious: 1. It takes up a large area of ​​the instrument panel, and both components need to be relatively large 2. The operation function is single, and each knob can only achieve a single function, which often cannot achieve the expected function well; 3. The operation is inconvenient, and the two knobs require multiple operations; 4. The wiring connection is troublesome, and the two components The location affects the connection line, resulting in the complexity of the line connection

Therefore, the traditional method of use also requires the measurement and control instrument to provide sufficient plane size, thus restricting the miniaturization and portability of the measurement and control instrument
