Rotary switches are a type of electromechanical switch used to control various electrical and electronic components. MB03S3NCGD is a rotary switch designed for the automotive and industrial uses. It has a single pole three position transfer switch that meets specifications for DIN rail mounting and is suitable for appliances and manual control.

The MB03S3NCGD rotary switch uses a single shaft and requires three 90° turns to complete a full rotation. It has a simple mechanical operation and a reliable switching mechanism. Two independent lever arms are connected to the rotating shaft, each coupling to a separate position on the outer switch housing.The rotary switch includes a spring intern for over travel prevention and prevents mechanical over run.

Application fields

The MB03S3NCGD is designed for harsh environments, and is suitable for use in challenging industrial settings. Its robust mechanical operation makes it ideal for controlling power, water, air, and oil systems. The switch is rated up to IP67 and features a metal housing, making it suitable for use in marine and offshore settings. It can also be used in wash down environments, such as kitchens or food production facilities.

In addition, the MB03S3NCGD is suitable for automotive settings such as automotive production lines, engine control systems, and vehicle audio systems. The switch is shock and vibration resistant and has a high cycling life, making it ideal for automotive applications.

Working Principle

The MB03S3NCGD rotary switch is composed of three main components, the shaft, cam, and spring. The shaft is connected to the lever arms and ring gear, which is attached to the cam. As the shaft is rotated, the cam is actuated and pushes the lever arms against the switch contacts, activating the circuit.

The spring is designed to keep the lever arms in the same position when the switch is not in use. This prevents contact damage and wear. When the switch is in use, the cam is actuated, pushing the lever arms against the contacts and allowing for the flow of electricity or current.

The MB03S3NCGD rotary switch is designed for long-lasting reliability. Its robust mechanical design and reliable switching mechanism make it suitable for harsh environments, making it ideal for various automotive, industrial, and marine applications.
