Abstract

Un circuito per segnalare lo stato di un interruttore elettrico (I), utilizzabile ad esempio come interfaccia di segnalazione portiera aperta per check. Il circuito comprende un transistore (Q) il quale lavora in rapporto di sottrazione di corrente rispetto all'elemento di segnalazione (D).(Figura 3).A circuit to signal the status of an electric switch (I), which can be used, for example, as an open door signaling interface for check. The circuit comprises a transistor (Q) which works in a current subtraction ratio with respect to the signaling element (D). (Figure 3).
