Micro relay 24 V 333/S5959 JCB, aftermarket

Micro relay 24 V 333/S5959 is an aftermarket part for the JCB machines.

This part is a micro relay for JCB machines with a 24 V system. According to sources, 333/S5959 is a 24 V micro relay superseded by the newer number 335/G9885. Micro relays take little space in the fuse and relay box and switch circuits such as lamps, fans, the horn or solenoids with a small control current. The relay coil must match the machine voltage: a 12 V relay burns its coil on 24 V, and a 24 V relay does not pull in on 12 V. A faulty relay stops the function working or makes it cut out now and then. Before fitting the relay in the fuse and relay box, compare the diagram and voltage on its case with the old relay. Micro relays must sit tightly against vibration, since a relay partly out of its socket makes the function cut out now and then. If a fault is suspected, swap it with a sound relay of the same type.

Fitting

If the socket contacts show oxide or melting, check the socket too, since a faulty socket heats the new relay as well. The relay is chosen by part number so that its voltage, current rating and pin layout match the old one.
