In a household appliance, it might be used to control the fan speed or to choose between different cooking programs on a stove or oven. In the automotive industry, it is often used to control the speed of a window motors.

The working principle of a rotary switch is relatively simple. The contact arm is attached to a shaft, which is connected to an actuator, such as a knob. When the actuator is turned, the shaft and contact arm rotate, causing the contacts to move from one position to the next. As the contact arm moves through its range of motion, it can switch between two or more terminals, depending on the type of switch.

The RBP12 403B03 N AD S series also has a number of accessories available, such as signal lamps and limit switches, which can be connected to the switch. These accessories are useful for indicating the current position of the switch, as well as providing an extra level of safety.

In summary, the RBP12 403B03 N AD S is an affordable and reliable rotary switch suitable for a variety of applications. It has three main terminals, one common and two opposite ones, and when the arm is turned it can connect all three. It is also available with a range of accessories, such as signal lamps and limit switches, to help improve its functionality. The RBP12 403B03 N AD S series is a great choice for those looking for a reliable and long-lasting rotary switch.
