Abstract
An electronic switch includes a sensor for sensing external conditions and an integrated circuit for evaluating the sensor signal from the sensor. The integrated circuit has a short circuit interrogation device and delivers a signal indicating the switch state of a load switch to an IC output. The integrated circuit transmits a short circuit signal indicating a short circuit to a short circuit display LED. The short circuit display LED is directly connected to another IC output terminal to display the short circuit so that an integrated circuit can operationally be switched between three LED displays for a switch state, a short circuit and a operation.
