Rotary Switches Application Field and Working Principles

Rotary switches are commonly used in the process industry, and they have become increasingly popular due to their versatility and ease of operation. They can be used to control a variety of processes, ranging from the operation of pumps and motors to the regulation of temperatures and other process variables.The most common type of rotary switch is the 77SPT36-01-1-04N model, which is used for various industrial applications. This switch is comprised of a rotor, which has internal contacts that are connected to the circuit board, and a switching mechanism that is actuated when the rotor is turned. The rotor is connected to a shaft, and when the rotor is turned, a set of external contacts on the circuit board is actuated to switch the state of the switch.The rotary switch is a very simple device that is used for many applications, from controlling high-powered electrical devices to regulating temperature and other process parameters. It has a simple design and is relatively easy to install, as it only requires basic wiring connections to be made. The number of connections depends on the type of switch and the number of poles.The working principle of a rotary switch is quite simple. When the rotor is turned, the contacts on the circuit board are actuated and electric current passes through them. Depending on the position of the rotor, the contacts can act as an on/off switch or as a voltage-variable resistor. The voltage passes through the contacts and the resistance varies according to the direction of rotation.The rotary switch is mostly used in operations that require frequent switching between several states, such as controlling AC motors, controlling temperatures and operating instruments. They are also used in applications that require the switching of power to more than two circuits.In the industrial sector, rotary switches are frequently used for controlling machine parts, such as turning motors on and off or controlling temperature in reactors. They are also used for opening and closing valves for various types of pumps.In short, rotary switches can be used for a variety of purposes, and the 77SPT36-01-1-04N model is a popular choice due to its versatility and reliability. It is relatively easy to install and operate, and it can be used for a wide range of applications. The working principle is quite simple, and it has proven to be an invaluable tool in the process industry.
