Which part of a motor vehicle is controlled by a rotary switch?

[DeAdaline]

Rotary switches control the front and rear fog lights of a motor vehicle. Definition of a rotary switch: A rotary switch is a type of switch that uses a rotating handle to control the opening and closing of the main contacts. There are two structural forms of rotary switches: single-pole single-throw and multi-pole multi-throw. Single-pole single-throw rotary switches are often used in conjunction with rotary potentiometers in applications, while multi-pole multi-throw rotary switches are mostly used for switching working state circuits. Function of a rotary switch: Essentially, a rotary switch is also a type of knife switch, except that the operating handle of a general knife switch rotates upward or downward in a plane perpendicular to the mounting surface, while the operating handle of a rotary switch rotates left and right in a plane parallel to its mounting surface. It can be used to connect or disconnect circuits, switch power sources or loads, measure three-phase voltage, and control the forward and reverse rotation of small motors.
