The oil level switch is designed to shut the engine off in the event the oil level drops. The oil level switch is
mounted to the engine crankcase.
A clogged or stuck oil level switch will allow the engine to run without or with a low oil level which can cause
damage to the engine. An engine with sludge oil caused by lack of maintenance can cause an oil level switch
to stick. Checking oil level prior to running the engine is good maintenance practice as well as changing
engine oil frequently.

Construction and Operation
The oil sensor is composed of the float, permanent magnet
incorporated into the float and oil sensor. In accordance
with the oil level, the float moves up and down.
When the oil is at the upper level the float moves up.
When the oil is at the lower level the float moves down. The
permanent magnet is closed to the lead switch, and the
lead switch is activated by the magnetic force.
