olie05 Posted August 30, 2006 Share Posted August 30, 2006 i'm looking for a pushbutton switch that can has resistance values instead of on-off. I guess it could be called a push button POT. It will be wired to an actuator... anyone know where to find such a thing? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted August 30, 2006 Share Posted August 30, 2006 like a switch that is the trigger button on an Xbox controller? Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted August 30, 2006 Share Posted August 30, 2006 If you don't care for adjustability, why not just a 2 position switch with the appropriate resistors in line? One resistor for each position. It's one of the switches with at least 3 connectors. Mario Quote Link to comment Share on other sites More sharing options...
olie05 Posted August 30, 2006 Author Share Posted August 30, 2006 its for a clutch... so i have to know how far the button has been depressed, so i know how far to actuate the clutch Quote Link to comment Share on other sites More sharing options...
Dragonfly Posted August 30, 2006 Share Posted August 30, 2006 Not quite push button but I work with on a daily basis what is basicaly a straight rheostat. By straight I mean it is not a round pot were you turn a knob but rather an aray of magnetic reed switches each one having its own resistance and as a magnet passes by each switch the resistance is changed causing the power/readout to change. What would probably be easier to do with what it sounds like you are trying to acheive would be to use a standard rheostat that has the capacity you want then modify a bracket and linkage to allow linear movement to rotate the shaft in the rheostat.

Dragonfly I was thinking about the rheostat idea... that should work. Quote Link to comment Share on other sites More sharing options...
redruM_0381 Posted August 30, 2006 Share Posted August 30, 2006 What you are looking for is a "Slide pot" Looks like this: http://cgi.ebay.com/50K-Alps-74mm-Audio-Taper-Slide-Pot-2-pieces_W0QQitemZ7573551694QQihZ017QQcategoryZ58164QQssPageNameZWD1VQQrdZ1QQcmdZViewItem Dirt cheap, and common. You could even salvage one out of an old rack stereo.. They used slide pots a lot for volume, etc. Quote Link to comment Share on other sites More sharing options...
