Abstract
Una estructura de interruptor de lengüetas de baja histéresis para sistemas indicadores de posición, que posee un elemento magnético móvil dentro de un recinto herméticamente cerrado, que comprende: un interruptor de lengüetas montado al exterior del recinto herméticamente cerrado, para ser normalmente accionado por el elemento magnético a un primer nivel de flujo magnético, y desactivado en un segundo nivel de flujo magnético al moverse el elemento magnético a proximidad del interruptor de lengüetas; una unidad de alimentación de corriente eléctrica alterna, y una bobina de hilo conductor arrollada en torno al citado interruptor de lengüetas para producir un flujo magnético alterno, que posee una amplitud que ajusta entre dichos primero y segundo niveles de flujo cuando se conecta a la citada unidad alimentadora de corriente alterna.
