Thermal overload switch from the sip compressor.

 Compressor is now retired but I still have this switch.

Keep your old compressor alive a bit longer

The SIP part number is 40639

Any questions feel free to call me.

I ALSO HAVE A 20AMP ONE, MINE USE TO BLOW A LOT WHEN THE WEATHER WAS COLD AND THE COMPRESSOR TOOK EXTRA AMPS TO FIRE IT UP.

JUST ASK, I can send out either the 18 or a 20 amp one........

If you want a second switch I can do the second one for £10, no more postage
