Liquid level switch, also known as water level switch, as the name implies, is a switch that controls the connection of the line through the liquid level. The float level switch uses a micro switch for contact output. When the angle of the line above the horizontal plane exceeds 28°, the steel ball inside the float level switch will roll and press the micro switch or leave the micro switch, so that the contact signal of the level switch ON or OFF is output.
