The invention relates an electronic switch for switching on and off high AC voltage between two connecting terminals. The switch includes two series-connected MOS floating gate transistors (20, 30; 20', 30'), that can block and establish the transmission path between the applied high AC voltage connecting terminals. A charge storage device (24, 27, 34, 37; 24', 34', 60) stores charges and is connected to each gate of the MOS transistors. Each charge storage device (24, 27, 34, 37; 24', 34', 60) is assigned a charge feeding device (40, 50; 50) for applying a predetermined quantity of charge to the charge storage device (24, 34; 24', 34'), which corresponds to a first switching state, and for removing a predetermined quantity of charge from the charge storage device, which corresponds to a second switching state. In this way, very low energy sensor outputs control high power AC voltage applied to the connecting terminals. This switch has utility in the automotive and other industries. |
