Electronic switch with main contacts actuated by rotary handle
ロータリースイッチは、従来の抵抗ポテンショメータの機能を模倣するロータリーパルスジェネレータの代わりに使用できます。. これらのロータリースイッチは、計器のフロントパネルやオーディオビジュアルコントロールパネルのヒューマンマシンインターフェイスで一般的に使用されます。. ロータリースイッチは、アナログポテンショメータの代わりに純粋なデジタルデバイスとして直交光学式エンコーダを使用します。. These rotary switches look similar to traditional or resistive potentiometers in appearance, but the internal construction of these rotary switches is completely digital and uses optical technology. Similar to traditional incremental encoder products, there are two quadrature output signals (channel A and channel B), which can be directly connected to the encoder processing chip.

Introduction to Electronic Rotary Switches
Electronic rotary switches are mainly installed on liquid and gas pipelines to adjust the flow and pressure of liquid and gas. During use, turning the handle drives the adjusting nut to rotate, and is connected with the left-handed thread of the valve through the left-handed thread. Drive the valve to move to the right or left to change the cross-sectional area of the right hole passage in the valve body cavity, thereby adjusting the flow and pressure of the liquid and gas in the upper outlet pipeline.

The use of electronic rotary switches
The electronic rotary switch is a switch that controls the on-off of the main contact by rotating the handle. There are also two structural forms of the rotary switch, which are unipolar unit structure and multi-pole multi-position structure. The unipolar unit rotary switch is often used together with the rotary shaft potentiometer in the application, while the multi-pole multi-position rotary switch is mostly used for switching the working state circuit.

How Electronic Rotary Switches Work
In a range, the resistance value is changed, and then there is a contact switch, which is the switch of old-fashioned TV sets and radios. For the fan, there are several gears, connected to several sets of lead wires of the fan winding, and changing the speed by changing the number of coil turns. The principle is similar to that of a potentiometer.

Structural characteristics of electronic rotary switch

Common band switches and multimeter shift switches are rotary switches. There are two structures: one is the BBM (Break Before Make) contact type, which is characterized in that the moving contact first disconnects the front contact and then connects the rear contact when transposition. There is a state in which both the front and rear contacts are disconnected: the other is the MBB (Make Before Break) contact type, which is characterized in that the moving contact has a state of contact with both the front and rear contacts when the position is changed. Then disconnect the front contact and keep in contact with the rear contact. In the circuit design, the appropriate rotary switch should be selected according to the circuit application and circuit safety.

Common Types of Electronic Rotary Switches
Because of its purpose, the rotary switch adopts a sealed structure as a whole, which has a certain waterproof effect, and can basically reach the waterproof level of IP65.
同時に, it is necessary to use a relatively hard and durable metal material, and there are 2 または 3 gears in the gear position. Such as AS series:
