Hey folks, Im trying to get a transistor to switch on a relay. the transistor is controlled by a 15k ntc. It works ok but as the risistance slowley decreases it triggers the coil in the relay very slowley so the contacts have a high resistance between them untill the ntc havs a small enough resistance to alow the foward voltage on the transistor to be full flow rate. Is there any way I can get it so the relay just works as on/off when it gets to a certian risistance? maybe some kind of regulator?
Im a bit of a newbie with electronics so cheers for any help!
