Perkins 4.203 Oil Pressure Switch

Our standard aftermarket single spade oil pressure switch fits Perkins 4.203 that take an earth supply from the engine block. It has a tapered screw thread and single spade type electrical connection for 12v or 24v systems.

On marine versions, Perkins would often isolate the engine block from the earth (-) supply and in these cases a twin spade oil pressure switch is needed. New ones are now hard to source, but we hope to have stock very soon.

Please note both of these aftermarket switches work the low oil pressure warning light (or alarm). They are not oil pressure gauge senders.
