English term or phrase: torsion spring over-centre mechanism
Hola a todos,

Mi duda puntual en este caso es si existe alguna expresión simple y corta en castellano para definir un mecanismo "over centre". Este es el contexto:

"Bistability as applied in the design of mechanical systems is more commonly said to be "over centre"—that is, work is done on the system to move it just past the peak, at which point the mechanism goes "over centre" to its secondary stable position. The result is a toggle-type action- work applied to the system below a threshold sufficient to send it 'over center' results in no change to the mechanism's state.

Springs are a common method of achieving an "over centre" action. A spring attached to a simple two position ratchet-type mechanism can create a button or plunger that is clicked or toggled between two mechanical states. Many ballpoint and rollerball retractable pens employ this type of bistable mechanism.

An even more common example of an over-center device is an ordinary electric wall switch. These switches are often designed to snap firmly into the "on" or "off" position once the toggle handle has been moved a certain distance past the center-point."

He escuchado expresiones como "mecanismo excéntrico", pero no creo que se trate de este caso según el contexto dado, por lo que agradeceré sugerencias de ingenieros mecánicos o expertos en el tema.

TIA.

Mecanismo "sobre-centro" del muelle de torsión


Explanation:
Hola,
Si bien lo traduje, realmente no conozco que se use el término.
Por lo que veo es lo que también se suela llamar "center-past" para el cual dí una sugerencia (ver link).
Encontré una referencia en portugués en dónde usan "sobre-centro".
A mi entender las posibilidades son o dejarlo en inglés, o traducirlo literal, ya que en el contexto se explica de qué se trata, por lo tanto nombrarlo en forma descriptiva como por ejemplo "mecanismo de bloqueo mecánico" no me parece que sea lo más apropiado.
Sds!
