Rotary switches are common components in electrical systems and are used to select the desired load or to route signals. The type 111-4T2 switch is particularly suitable for demanding switching applications, thanks to its relatively high dielectric strength and current rating. The 111-4T2 switch is a four-pole, twelve-position rotary switch, which allows up to twelve different circuits to be connected or disconnected. This type of rotary switch features an insulated rotating shaft with a series of contacts attached to the end. As the shaft is turned, the contacts are engaged and selectively open and close the circuits.

The major application field for the 111-4T2 switch is in automotive industry. It is mainly used for system-level switching in cars and trucks. It is used to switch power from the battery power to the car’s electrical systems. It is also used to switch between the 12-volts and 24-volts power sources. Additionally, the switch is used for switching signals between components in automotive systems, such as ABS and airbags. Furthermore, it is used for switching between two different power sources, such as gas and electric.

The 112-4T2 switch is also often used in industrial automation systems. It can be integrated into automated systems to enable switching between different sources of power. It can also be used to switch between various process control devices or data acquisition systems. Additionally, the switch can be used to route signals between various components used in machine controls.

The 111-4T2 switch is designed to be robust and reliable. It is capable of withstanding operating temperatures of up to 125°C and a rated voltage of up to 250VAC. The contacts are gold plated and feature an external latching mechanism to ensure a secure connection. Additionally, the switch is designed to be shock resistant, vibration resistant and dust resistant. This enables the switch to be used in harsh industrial environment.

The 111-4T2 switch operates using two basic principles. The first principle is continuity. As the shaft is rotated, the internal contact blades move allowing electrical connections to be made and broken. The second principle is resistance. The switch has two electrical terminals connected to each contact blade. When the blade is moved, the resistance between the two terminals is constantly changing, thus allowing electrical signals to be routed.

In conclusion, the type 111-4T2 switch is a reliable and versatile rotary switch designed for switching circuits and routing signals in automotive and industrial applications. It features a robust construction and is designed to withstand harsh environmental conditions. Additionally, it operates on the principles of continuity and resistance, allowing it to route signals and power as needed.
