The report on injuries to children inserting things in to receptacles and getting injured cited burn injuries. This would mean that they had to have two conductive objects. The design of the TR receptacle that I played with does not prevent the insertion of two objects. When this was proposed I thought that if you did not insert something in each slot at the same time the shutters would not open. That appears not to be the case. You can put an object in one slot and the shutter will not open, but when you put a second object in the other slot, both shutters open. If we are going to have to have these things, then the shutter design should require that you push against both shutters at the same time.
