What is a float switch?
September 17, 2014 11:40PM
A float switch is a common device that is used as an indicator in pumps or other devices that operates with the use of water. This device detects the current level of water and sends an alarm or acts as a switch for other devices to function.

Your coolant light of your 97 sunfire 2.2 came on and it is full with radiator fluid what else can this be the light wont go off?
There is a sensor that is in the overflow bottle that may be bad causing the "low coolant light" to illuminate. The coolant level switch is located on the bottom side of the coolant tank. The switch contains a reed switch and a magnetic float. When the coolant level is normal, the float rests away from the reed switch, causing the switch to be open. When the coolant level decreases in the coolant recovery tank below a specified level, the float rests on the reed switch and the switch closes, illuminating the LOW COOLANT light. The coolant level switch is a part of the coolant tank. If the switch needs to be replaced, the coolant tank must be replaced.

How do you connect float switches for a single phase motor through contactor and Over Load Relay?
you would wire a float switch into the control circuit i.e, the contactor coil (which is relatively low current but rated at least for the control voltage,, in most cases 120VAC). also in the same circuit would be the overload contacts. if the overload trips and/or the float switch opens then voltage is removed from the contactor coil

What is a buchholz relay on a three phase transformer?
This is a sudden pressure relay. If the transformer is overloaded, it can cause gassing, which will be detected by this (mechanical) relay. This Question deserves a more elaborate answer A Buchholz relay consists of a chamber containing two pivoted floats; an upper float and a lower float. The lower float is fitted with a flap which will deflect that float if a pressure wave passes through the relay's chamber. The relay is located in an inclined pipe leading from the top of the transformer to its expansion vessel above the transformer. An oil leak in the transformer will eventually cause the oil level in the Buchholz relay's chamber to fall. As the oil level falls, the upper float pivots downwards, closing a mercury switch attached to the float. This activates a warning (alarm) in the substation, but does not disconnect the transformer. If the oil level continues to fall, the lower float also pivots downwards, and a mercury switch attached to that float causes the protection system to disconnect the transformer. In the event of minor burning within the core of the transformer, gas is generated which bubbles upwards towards the expansion vessel, some of which gathers within the top of the Buchholz relay's chamber. As the gas accumulates, it causes the top float to pivot downwards, closing a mercury switch attached to the float. This activates a warning in the substation, but does not trip the transformer. In the event of a major flashover between windings, a pressure wave is set up in the oil. This pressure wave passes through the Buchholz relay's chamber, and causes a flap attached to the lower float to deflect that float, closing its mercury switch, causing the protection system to disconnect the transformer immediately. To summarise. The upper float acts provides a warning of a drop in oil level or an accumulation of gas. The lower float acts to disconnect the transformer if the oil level continues to drop, or a pressure wave passes through the chamber. (A valve at the top of the Buchholz relay allows any accumulated gas to be collected for testing, as the nature of the gas can be used to indicate the nature of the fault generating that gas(
