Abstract
Improvements in electrical switches, characterized in that they comprise a first rigid contact plate, a second rigid contact plate parallel to the previous and separated from it, a series of switching elements located between both plates, each of which has the form of a block of elastic insulating material that contains inside conductive particles such that when the block is in a relaxed state do not make contact with each other, but when the block is subjected to compression, above a certain amount, they come into contact each other, making the block conductive, said conductive elements adjusting both to the first and the second plate, guide means that allow to keep the first and second plate generally parallel to each other, while allowing movement relative approach or distance of one plate with respect to the other and some limits that limit the separation maximum n between the plates when these are removed under the spring action of the switching elements, thereby limiting both the restoration of said elements to their relaxed to an amount in which these elements are no longer conducting state.
