What is Rotary Switch

The rotary switch can be used to replace the rotary pulse generator with the analog function of the traditional resistance potentiometer. These rotary switches are usually used in the man-machine interface of the front panel of the instrument and the audio-visual control board. The rotary switch adopts the orthogonal optical encoder as the pure digital device to replace the analog potentiometer. These rotary switches are similar to the traditional or resistance potentiometer in appearance, However, the internal structure of these rotary switches is completely digitized and optical technology is used. Similar to the traditional incremental encoder products, there are two orthogonal output signals (channel A and channel B), which can be directly connected with the encoder processing chip.

Structural Features of Rotary Switches

The common band switch and the shift switch of the multimeter are rotary switches, which have two structures: one is BBM (break before make) contact type, which is characterized in that when shifting, the moving contact first disconnects the front contact and then connects the rear contact, in which there is a state of disconnection from both the front and rear contacts: the other is MBB (make before break) contact type, Its feature is that during transposition, the moving contact has a state of contact with both front and rear contacts, and then disconnect the front contact to maintain contact with the rear contact. The switch shall be selected according to the purpose of the rotating safety circuit.

purpose and working principle for Rotary Switches


Rotary switch is a kind of switch that controls the on-off of the main contact point by rotating the handle. There are also two structural forms of rotary switch, namely unipolar unit structure and multipole multi bit structure. Unipolar unit rotary switches are often used together with rotary shaft potentiometers in applications, while multipole multi position rotary switches are mostly used for switching lines in working state.

working principle

In a certain range, the resistance value is changed, and then there is a contact switch, which is the switch of old-fashioned TV and radio. In the case of fan, there are several gears, which are connected with several groups of outgoing lines of fan winding, and the speed can be changed by changing the number of coils. The principle is similar to that of potentiometer.
