A wall mounted cover plate (40) conceals an electrical circuit (50) capable of sensing the field provided by a covered switch (30) or electrical socket circuit. When power is lost at the wall circuit the electrical circuit (50) senses the loss of power and activates one or more LEDs (90A) to provide emergency illumination. The electrical circuit (50) is self contained and does not require stand-by energy so that the batteries (58) are long lasting.
Plaque de recouvrement (40) montée sur un mur, qui cache un circuit électrique (50) capable de détecter le champ produit par un commutateur couvert (30) ou un circuit de douille. Lorsque courant ne parcourt plus le circuit situé dans le mur, le circuit électrique (50) détecte la perte de puissance et excite une ou plusieurs diodes électroluminescentes (DEL) (90A) destinées à produire un éclairage d'urgence. Le circuit électrique (50) est autonome et ne nécessite pas d'énergie d'attente si bien que les piles (58) durent longtemps.
