2A1908-2 is a type of temperature switch which is compatible with many water heating systems. The main purpose of this device is to keep the temperature of the water at a safe and suitable level. It is usually installed in the top of the tank and connected to the cold and hot water feed pipes to control the temperature of the water. It is an important component of the hot water systems used in residential and commercial applications.

This switch is designed to keep the water between two different temperature levels and stop the water flow if it exceeds the predefined range. There is a mercury switch which senses the temperature of the water and shuts off the heater when the temperature of the water reaches the predefined level. It provides optimal performance and reliability for long-term usage.

This switch is suitable for the application of water heaters, immersion heaters, oil filled radiators, hot water tanks, and central heating systems. It is durable and long lasting and also provides excellent reliability for these applications. It is easy to install and requires minimal maintenance. It is also resistant to vibration and shock. It is also compatible with a variety of other water heating systems.

This type of switch works on the principle of the Jehlein Method. This method measures the temperature of the water in the tank and then delays the temperature switch by a pre-defined amount of time. If the temperature is higher than the set level, it will open the circuit, thus stopping the water flow. Jehlein Method works by creating a voltage on a coil that is proportional to the temperature of the water. This coil then supplies a signal to the contacts of the switch.

2A1908-2 is a reliable and effective temperature switch with a wide range of applications. It is suitable for the application of water heaters, immersion heaters, oil filled radiators, hot water tanks, and central heating systems, making it an ideal choice for any residential or commercial installation. It is easy to install and requires minimal maintenance due to its durable construction and long lasting performance.
