MRT23-BC

Rotary switches are electro-mechanical switches that can open or close electrical circuit paths in just one or a few discrete positions. The MRT23-BC rotary switch is a versatile model that has varied applications in the industrial and automotive markets. This article will examine the application field and working principle of the MRT23-BC.

Application Field

The MRT23-BC rotary switch is designed for low-current and low-voltage applications. In industrial applications, it is commonly used for controlling the speed of electric motors. The MRT23-BC features various speed grades (A, B, C and D) and three adjustable torque settings. It is also capable of controlling the direction of rotation, enabling forward and reverse movement.

The MRT23-BC is also useful in automotive applications. It is commonly used to control the speed and direction of automotive engines. The MRT23-BC is equipped with three programmable speed and torque settings, enabling it to be used in various applications such as turbo, electric, and gas engines. It is also designed to be dustproof and waterproof, making it suited for use in wet and dirty environments.

Working Principle

The MRT23-BC rotary switch operates on a simple two-phase principle. Two pairs of contacts are used, one for the current (hot) and the other for the control or load. When the switch is in its rest position, the curved parts of the control contacts are in line with each other, allowing the current to flow through the switch and the load. When the switch is rotated, the curved sections of the control contacts are disconnected and the current is diverted, stopping the flow of the current to the load.

The MRT23-BC also features a torque adjustment. This feature is used to program the torque settings, which can be adjusted to control the speed of the switch. The higher the torque setting, the faster the switch will turn. Conversely, the lower the torque setting, the slower it will turn.

Conclusion

The MRT23-BC rotary switch is a versatile device that offers a wide range of applications in the industrial and automotive markets. It is capable of controlling the speed and direction of electric and automotive motors, and is designed to be dustproof and waterproof. Its working principle is based on a simple two-phase design that utilizes contact pairs to divert the current flow to the load. It also features adjustable torque settings, allowing the user to adjust the speed of the switch.
