Understanding the Inner Workings of a Piggyback Float Switch
Float switches are ingenious devices that have been used for decades to control liquid levels in various applications. One type of float switch, known as the piggyback float switch, has gained popularity due to its simplicity and effectiveness. But how exactly does this nifty little device work?
To comprehend the inner workings of a piggyback float switch, we must first understand its basic components. At its core, this switch consists of a buoyant float attached to a lever arm. The lever arm is connected to an electrical switch, which is responsible for controlling the flow of electricity. When the liquid level rises or falls, the float moves accordingly, causing the lever arm to pivot. This movement triggers the electrical switch, either opening or closing the circuit.
The piggyback float switch gets its name from an additional feature that sets it apart from other float switches. It has a second switch, commonly referred to as the “piggyback switch,” which is attached to the main switch. This secondary switch is used to control a separate electrical circuit, providing an extra level of functionality.
The primary switch of a piggyback float switch is typically used to control a pump or a valve. When the liquid level reaches a predetermined point, the float rises, causing the switch to close the circuit and activate the pump or open the valve. This allows the liquid to be pumped out or drained until the level drops, causing the switch to open the circuit and stop the operation.
The piggyback switch, on the other hand, can be utilized for various purposes. For instance, it can be connected to an alarm system to alert users when the liquid level reaches a critical point. Additionally, it can be used to control a secondary pump or trigger a warning light, providing an extra layer of protection and control.
One of the key advantages of a piggyback float switch is its versatility. It can be used in a wide range of applications, including sump pumps, sewage systems, water tanks, and even industrial processes. Its simple yet effective design allows for easy installation and reliable operation, making it a popular choice among professionals and DIY enthusiasts alike.
To ensure the proper functioning of a piggyback float switch, regular maintenance is crucial. Over time, debris and sediment can accumulate on the float, affecting its buoyancy and hindering its movement. Therefore, it is recommended to clean the float periodically and inspect the switch for any signs of wear or damage.
In conclusion, the piggyback float switch is a remarkable device that offers a practical solution for liquid level control. Its ingenious design, consisting of a buoyant float and an electrical switch, allows for precise monitoring and control of liquid levels. With its additional piggyback switch, this versatile device provides an extra layer of functionality, making it an indispensable tool in various industries.
