Rotary Switches

Rotary switches are electromechanical devices that allow a user to select from a series of multiple circuits, by controlling a rotary or rotating handle. They are also referred to as multiselect switches, with 44M45-09-1-03N being a specific type. Used in electrical devices, these switches allow users to select from a range of possibilities, using contacts to open and close the circuit.

Application Field and Working Principle

44M45-09-1-03N rotary switches are particularly suitable for applications in safety-critical areas such as the automotive, industrial, medical and aerospace industries. The switch operates with a process of ‘make before brake’, meaning it switches off the previous contact before connecting to the next contact. This is done to prevent any type of short circuit or incorrect connection and provides improved reliability, selectivity and isolation.

The 44M45-09-1-03N rotary switch has 3 poles with 3 positions. Each position is equipped with two stationary contacts. The central contact is the moveable contact which is rotated by the user in order to select between the different and independent circuits. Movement of the central contact allows for the arrangement of additional contacts for greater complexity and clearly labeled poles for easy identification.

The 44M45-09-1-03N rotary switch is designed as an intermittent switch, meaning it is only intended for use in circuits with momentary operation, with no extended periods of being switched on. This is usually achieved by using a lever or cam to reset the switch after each operation. This type of switch is rated up to 10 Amps at 250V AC and is available in various body sizes and materials, including all-metal and plastic cases.

The 44M45-09-1-03N rotary switch is capable of having as many as nine positions, each of which can be selectively opened or closed. This makes it very useful in a variety of applications, ranging from lighting controls to on/off signals, power switching, and more. Additionally, they can be used to activate multiple circuits simultaneously when needed, providing a single-pole, multi-throw switch.

In industrial applications, the 44M45-09-1-03N rotary switch can provide reliable, secure switching in harsh environments. It has a wide operating temperature range, allowing for use in extreme temperatures. The switch is also designed for corrosion resistance, making it ideal for use in areas where there is a high level of moisture or dust.

The 44M45-09-1-03N is a versatile, popular rotary switch choice for many electrical devices. It provides versatile switching of circuits, reliable operation, and easy installation. As such, it is a preferred choice for use in a wide range of application fields.
