Description

Description Background

The float switch supports manual adjustment between lower-open and upper-open states. The operating mode can be identified by the mark on the float ball: when the mark faces upward, it indicates the lower-open state; when the mark faces downward, it indicates the upper-open state. The factory default setting is lower-open.

To change the setting to upper-open, remove the circlip beneath the float ball, take the float ball off the rod, rotate it 180°, and reinstall it with the mark facing downward. After securing the circlip, use the buzzer mode of a multimeter to verify the switching function: the multimeter should remain silent when the float is at the bottom and sound when the float is at the top, confirming that the adjustment is correct.

Features

Can the position of the float ball be moved arbitrarily?

No. The position of the float ball is fixed, with circlips limiting it up and down. Moving the circlips is useless because the reed switch contacts inside are immovable.

Can the float switch directly control water pumps, solenoid valves, or alarms?

No. Because the current of the reed switch contacts inside the float switch is small, controlling large loads will burn them out. To control solenoid valves or alarms, a small relay is needed. To control a water pump, a small relay and an AC contactor (matching the power of the water pump) are required.

What is the control range of the float switch?

There are dimensions and control ranges listed below on our webpage. If the dimensions below are not suitable for you, you can request a non-standard customization, and there is no limit to the quantity.
