Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a novel liquid level relay. Background Technology

[0002] A liquid level relay is a type of relay that controls the liquid level. Internally, it contains electronic circuitry and operates on the principle of utilizing the conductivity of liquid. When the liquid level reaches a certain height, the relay activates and cuts off the power. Conversely, when the liquid level falls below a certain level, the relay reconnects the power to the water pump, enabling automatic control. However, existing liquid level relays on the market have structural shortcomings: their design is unreasonable, and they are often integrated units requiring rewiring and refixing during replacement. This process necessitates the use of screwdrivers or similar tools, making the operation cumbersome, inconvenient, and impractical. Utility Model Content
