Frequently Asked Questions
Q: What is a horizontal float switch water level sensor used for?
A: A horizontal float switch water level sensor is used to automatically detect and respond to changes in liquid levels inside tanks, reservoirs, or containers. When the water rises or falls to a set point, the float switch triggers connected devices such as water pumps, alarms, or indicator lights — making it ideal for hydroponics, aquariums, fish tanks, pool controllers, pet bowls, irrigation systems, and DIY electronics projects.
Q: Is this float switch compatible with both 12V and 24V systems?
A: Yes, the HpLive float switch supports both 12V and 24V DC input voltages, making it compatible with a wide range of automatic water pump controllers, tank monitoring systems, and low-voltage DIY setups.
Q: Does this water level sensor contain mercury?
A: No. This float switch is completely mercury-free, making it a safer and more environmentally friendly choice for home and hobby water management applications.
Q: How do I install the horizontal float switch?
A: The horizontal float switch is designed to be mounted on the side wall of a tank or reservoir at the desired water level point. When the liquid reaches the sensor, the internal float actuates the switch mechanism, triggering your connected device. No battery is required — it operates directly from your system's 12V or 24V DC power supply.
