Rotary Switches: 42S36-03-1-07S application field and working principle

Rotary switches are among the most common types of switches, often used in long lasting applications and normally robust enough to handle different types of situations. This article will discuss the application field and working principle of the particular rotary switch, model # 42S36-03-1-07S.The 42S36-03-1-07S is a rotary selector switch, seven-position switch, with a total rated current at 1600 Amps and an operating voltage of up to 600 Volts. This particular switch is most commonly used in the power supply industry, such as the distribution and protection of panel wiring, motors and other electrical components, as well as in lighting panels and control systems.More specifically, the 42S36-03-1-07S is a three-deck switch with a four position top rotor, three position lower extra-duty rotor, and two position flange type actuator. In other words, the switching mechanism has two levels, the first of which contains a four-way dial for selecting between different positions and the second of which is a three-way dial for directing high-current loads if necessary.As far as the working principle is concerned, the 42S36-03-1-07S rotary switch is designed to throw a connection or break it when selecting the desired position. It is achieved through the combination of contact block, rotating drum and hub. A contact block usually consists of several spring type contacts which are mounted inside the cage along with a coil spring assembly. The rotating drum is mounted to the rotor and when the user turns the switch, it revolves within the stationary sleeve along with a hub. The hub operates the contact block and rotates it in the process.The 42S36-03-1-07S however, comes with a triple pole, double throw contact block. This means that if an electric current is passed through the switch, it will be diverted in one of two possible connections. Therefore, when the switch is turned on and positioned to the required position the current is allowed to flow according to the contacts present in the switch. The contacts are responsible for directing the connection between the poles and the load passing through them.When the switch is turned off the contact block is held in place by the mechanical coil spring and the electrical current passing through it is switched off. The contact block will then return to its closed position and the current shuts off.The 42S36-03-1-07S rotary switch is an important device that is needed in any electrical related applications such as motor control, circuit protection, and other applications related to the power industry. It has proved to be a reliable and robust device, capable of handling any current or switch into one of multiple desired positions. Its application field and working principle have made it an important aspect of any energy related operation that requires control and uninterrupted supply of power.
