Externet Posted January 24, 2013 Share Posted January 24, 2013 Is there any commercial device used in industry, equivalent to mechanical hysteresis ? A device that snaps mechanically or hydraulically, to two states like a toy clicker, or a 'klixon' thermal switch ? -A mechanically bistable device like a wall switch, unstable at its center position- Link to comment Share on other sites More sharing options...
swansont Posted January 24, 2013 Share Posted January 24, 2013 A relay is an electro-mechanical example. Link to comment Share on other sites More sharing options...
InigoMontoya Posted January 25, 2013 Share Posted January 25, 2013 Ummm.... A toggle switch? Link to comment Share on other sites More sharing options...

Hydraulic systems can use delay valves, so I guess you could consider that a "device" for imparting hysteresis. (Undesired hysteresis is actually a common problem in hydraulics.) Mechanical systems would have it built into the design of the mechanism. Link to comment Share on other sites More sharing options...
swansont Posted January 28, 2013 Share Posted January 28, 2013 A ratchet would probably be another mechanical example. Link to comment Share on other sites More sharing options...
chilehed Posted February 1, 2013 Share Posted February 1, 2013 Hysteresis is a characteristic of industrial devices, and in fact all devices used in industry exhibit it to some degree. Link to comment Share on other sites More sharing options...

Only an ideal spring does not have any hysteresis. But I think you are after something else... Edited February 6, 2013 by J.C.MacSwell Link to comment Share on other sites More sharing options...
Externet Posted February 7, 2013 Author Share Posted February 7, 2013 Thanks, gentlemen. I came up with an hysteretic mechanism, but appreciate your inputs. ----> A plastic pipe with a ball bearing inside and weak magnet end caps. Link to comment Share on other sites More sharing options...
Externet Posted February 7, 2013 Author Share Posted February 7, 2013 Sorry, another brain fart from poor English : shoud say bearing ball , or steel ball above instead of ball bearing. Link to comment Share on other sites More sharing options...
