Abstract

Interruptor térmico para el control de los circuitos de las lámparas de descarga eléctrica a baja presión que contienen contactos cooperantes uno de los cuales por lo menso va montado en un elemento bimetálico caracterizado porque a la temperatura ambiente este elemento tiene forma cóncava estando las partes de semejantes de este elemento dispuestas de tal manera que cuando el elemento alcanza la temperatura de funcionamiento deseada la concavidad se invierte súbitamente provocando un movimiento relativo rápido entre los contactos.Thermal switch for controlling the circuits of low-pressure electric discharge lamps that contain cooperating contacts, one of which is at least mounted on a bimetallic element characterized in that at room temperature this element has a concave shape, the parts being similar. of this element arranged in such a way that when the element reaches the desired operating temperature the concavity suddenly reverses causing a rapid relative movement between the contacts.
