Where do I go from here. (I hadn't realised it was coming from China or I would have shied away) The description says: "12V model with non-polarised (reversible) power terminals for easy wiring ". It also says it has a "relay output". II should guess the red and black for power leads and the other three connect to single pole double throw relay. You might need to connect it to a power supply and expose it to gas to be sure which two represent the n/o contact. Or you could just join the two which are currently shorted together and use with the one that isn't for a normally open switch if you need one. -- Roger Hayter |
