Small Float Switch Float Switch is a small simple structure, easy to use the level control components, it has a complex circuit, will not be disturbed, as long as the material selection is correct, of any kind of liquid, pressure, temperature can be used.

 Liquid nature of the relationship between the liquid and the float ratio is not the same time, float location will change the action, the general SG-hour than water, float immersed in the liquid part will be relatively stronger.

Float switches reference to the proportion of water (SG = 1) so used to be considered in the selection of liquid level float proportion of SG, certainly greater than the specifications indicated float, otherwise, the float switch can float.
High viscosity of the liquid does not dry up, the general should be selected larger diameter float.
Float switch is the use of magnets to sense magnetic reed switch, so the measured level should be no iron, otherwise the team will affect the float switch properly.
