Inquiry (采购产品): Thermocouple for mercury vapour switch Your company name appears on the plastic housing of the mercury vapour switch on my domestic central heating boiler so I assume you are the makers. The switch is type 3094-101. The boiler is Potterton Mk2 F made in 1983. The Potterton part no. is 402836. British Gas No. 3880960. I think the mechanical part of the switch is working ok, but the mercury vapour thermocouple is faulty. Is it possible for you to supply the thermoucouple, that is the mercury phial + coil + cap, but without the rest of the switch which in UK costs a fortune (£93 + vat) Thanks **** Hidden Message ***** Lindsay Ferguson 3 Glebe Meadow Overton BasingstokeRG25 3ER GBR Company: private individual Title: Mr Phone: 0044 1256 771208 E-mail: lindsay_ferguson@btopenworld.com **** Hidden Message ***** lindsay_ferguson@btopenworld.com
