A403S1RNCB rotary switches, also known as three-way switch, are control units that allow the user to select from three different switch positions. It is ideal for applications requiring three different power sources, such as a three-speed fan, or where more than one device needs to be controlled at the same time. It consists of a three-position, rotatable shaft and three different circuit contact strips mounted on the inner side of the plastic housing.

The application of A403S1RNCB rotary switches includes motor, fan and light control, as well as street light switching, automotive control, and HVAC applications. The switches are available in various configurations and provide a wide range of voltage and current ratings, which makes them suitable for most applications.

A403S1RNCB rotary switches are mainly composed of a rotary actuator and a stationary rotator, which are connected with a single-ended fixing bolt. When the current is passed through the actuator, it rotates a contact point, which is connected to a rotary sleeve that is fastened on the device body. When the switch is in the "off" position, the contact point touches a set of stationary pins, so that the current is not passed through. When the switch is in the "on" position, the contact point detaches from the stationary pins, allowing current to pass through the switch.

The A403S1RNCB rotary switches can be operated manually with a screwdriver or a 4mm hex key. It can also be operated automatically with a motor. They are available in various sizes and shapes and come with different contact layouts and contact materials. The contact layout determines the number of positions the switch can operate, while the contact material determines the contact frequency and resistance.

A403S1RNCB rotary switches are among the most reliable and cost-effective options available. With their robust construction and reliable operation, they can easily withstand extreme weather and vibration. In addition, they can be easily customized to suit specific applications.

A403S1RNCB rotary switches are widely used in various industries, such as electric power, marine, automobile, medical technology and communication. They are highly preferred for several reasons, such as reliability, compactness and cost-effectiveness. Moreover, these switches offer superior electric load capacity and a wide range of voltages, which makes them suitable for use in most applications.
