The funnel-type level switch includes a funnel, and the weight varies depending on the amount of piston cooling oil flowing into the funnel and the amount discharged. Therefore, the lever-type switch is operated according to the weight.

The level of the piston cooling oil is formed by the difference between the inflow amount and the exhaust amount of the piston cooling oil, and the piston cooling oil is statically discharged. The operation is based on the difference in capacitance between touching and not touching the capacitive level switch.
