Abstract
Acoustic and luminous warning for the test button of the differential switches. It consists of an electronic circuit added to a differential switch. The device warns after 30 days of operation, according to une en 61008 standard by means of an intermittent visual signal and an acoustic, buzzer. The start of the elapsed time account is made by pressing the test button of the differential. The device has the mission of indicating to the user when the test button must be pressed to check the correct functioning of the differential switches. According to une en 61008 standard. If you do not press nothing happens but we have the warnings, acoustic and light on until you press the test button. (Machine-translation by Google Translate, not legally binding)
