Is there any industrial device equivalent to mechanical hysteresis ?

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-

A relay is an electro-mechanical example.

[InigoMontoya]

Ummm.... A toggle switch?

Yes, but your question is ambiguous.

 

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.

A ratchet would probably be another mechanical example.

Hysteresis is a characteristic of industrial devices, and in fact all devices used in industry exhibit it to some degree.

A spring...to the degree that it is also a damper (almost insignificant for a good spring) . Only an ideal spring does not have any hysteresis.

 

But I think you are after something else...

Thanks, gentlemen.

 

I came up with an hysteretic mechanism, but appreciate your inputs.

Sorry, another brain fart from poor English : shoud say bearing ball , or steel ball above instead of ball bearing.
