waste oil furnace LIMIT SWITCH biodeisel bio-DIESEL

PLEASE READ THE FULL DISCRIPTION BEFORE BIDDING      this auction is for  (ONE SWITCH ONLY ). this is a  5/8 inch dia. limit switchs to control the heat pads or rods used to preheat waste vegitable oil or waste oil for waste oil furnaces. these can be mounted with two prong clips or with thermal adhiesive. for real tight area's the terminals can be cropped and leads sodered directly to the post studs. I personaly use these on my three lenair furnaces. my fu rnace company charges  $ 56.50 per limit switch which forced me to purchase these from another sorce.  ( currently I am down to about 13 of these and will not be reordering as I have kept enough for my own use.) these can also be used to preheat waste vegitable oil for biodeisel prossesing. these switch's can handle 120 volts a/c as well as any d/c current that you want to put threw them. these switchs are very easy to wire in, just follow your original wiring diagram  or for new applications all you need to do is wire your hot lead to one side of the switch and then continue the lead from the second terminal to your heat pad and run your common for a/c or ground for d/c from your pad back to your power supply. then mount switch directly to your preheater block. the switch will heat up with your block and turn off the power when it reach's 165 F and turns back on when the block drops to 150 F    I will combine shipping for mutipal item's. shipping is  $ 1.55 for the first switch and I will calculate for multipal item's after your order. shipping insurance is recomended as well as tracking, both are an additional cost to shipping price. if tracking and insurance isn't taken and your item is lost, broken, or stollen, you will be on your own. I take no responability for the shiping once it leaves my hands.  ALSO,,,,, SHIPPING OUT SIDE OF THE U.S.A. WILL BE A LARGER AMOUNT THEN REGULAR SHIPPING

thanks for looking at my auction and happy bidding !!!!                   all bidders outside of the u.s.a. will pay for any additional shipping cost to include tax's and terrifs
