Rotary switches can be used to replace the traditional resistance potentiometer simulation function of the rotary pulse generator, these rotary switches are usually used in the instrument front panel and audio and video control panel man-machine interface, rotary switch using orthogonal optical encoder as a substitute for analog potentiometer , These rotary switches are similar in appearance to conventional or resistive potentiometers, but the internal construction of these rotary switches is fully digital and uses optical technology. Similar to the traditional incremental encoder product there are two orthogonal output signals (channel A and channel B) that can be directly connected to the encoder processing chip.
Rotary Switch Product Overview
Rotary switches can be used to replace the traditional resistance potentiometer simulation function of the rotary pulse generator, these rotary switches are usually used in the instrument front panel and audio and video control panel man-machine interface, rotary switch using orthogonal optical encoder as a substitute for analog potentiometer , These rotary switches are similar in appearance to conventional or resistive potentiometers, but the internal construction of these rotary switches is fully digital and uses optical technology. Similar to the traditional incremental encoder product there are two orthogonal output signals (channel A and channel B) that can be directly connected to the encoder processing chip.
Rotary switch use
Rotary switch is a rotary handle to control the main contact off a switch. There are two kinds of rotary switch structure, namely, unipolar unit structure and multi-pole multi-bit structure. Unipolar unit rotary switch in the application often used with the rotary potentiometer, and multi-pole multi-bit rotary switch used for working state line switching.
Rotary switch works
In a range of conversion resistance value, and then there is a contact switch, which is the old TV and radio switch, now the fan is a few stalls, then the fan winding several sets of lead, by changing the coil The number of turns to change the speed, the principle and the potentiometer similar.
Rotary switch structure characteristics
Common band switch and universal meter shift switch are rotary switch, its structure has two kinds: one is BBM (Break Before Make) contact type, which is characterized in the transposition when the contact first disconnect the front contact And then connected to the rear contact, during which there is a break with the front and rear contacts are the state: the other is MBB (Make Before Break) contact type, which is characterized in the transposition when the contact has a contact with the front and rear contacts The And then disconnect the front contact, and keep contact with the rear contact state. In the circuit design should be based on circuit use and circuit safety to select the appropriate rotary switch.
Rotary switch common type
Rotary switch, because of its use of the relationship, the overall use of sealed structure, there is a certain waterproof effect, the basic can achieve IP65 waterproof level.
At the same time need to use more durable and durable metal material, in the stalls have 2 or 3 file difference. Such as AS series: common types of rotary switches
