Thanks Gents! Sadly the contacts on these relays are recessed so the paper trick doesn't fit :( The contact surfaces are rare metal plated so I don't want to be too harsh with them - there seems to be a powdery deposit on some of them. Possibly oxide but I don't think so. I did another relay dismantle this afternoon, this time one with an auxiliary contact set added on the top. Doing the relay was just like the last one, but I could find no way of getting at the auxiliary contacts short of busting the plastic moulding. The contacts were bad, which is why I pulled it out, but I had in the end to try and flood the inside with contact cleaner / de-oxidiser and even getting that 'inside' was flaky - obviously essentially sealed. However working it by hand with the switch cleaner floating around in the end gave a good contact, but not a satisfactory solution really. Meanwhile if anyone knows a source of Siemens relays at a sensible price: Main relay 3TH 2031-0BB4 (3 N/O & 1 N/C 24v DC coil) Aux Block 3TX442-2A (2 N/O & 2 N/C) please let me know. They need really to have the same numbering scheme as the following pictures - the are a few around marked up L1 L2 L3 but I feel that is just going to lead to confusion in the future |

awemawson I tried looking for the part numbers that you listed and I think I may have found something. Here is the link to it. http://www.ebay.fr/sch/sis.html?_nkw=Siemens+3TH2031+0BB4+Schutz+mit+Hilfsschutz+3TX4422+2A+&_itemId=110846361606 I will continue to keep looking to see if anything else shows up at a reasonable price. Cheers :beer: Don |
