Abstract
Improvements in logic circuits, characterized in that said circuits comprise a series of type switches, as many questions as the circuit can verify at the same time, each one of which is associated with a question, which can have as many answers as the switch has positions, at least one of the positions corresponds to the logical answer to the question formulated and electrically connected, preferably by means of a printed circuit board, the positions of the different switches that correspond to the logical answers so that the formed circuit is closed by said switches when said logical answers have been selected, then feeding the electrical source associated to the circuit to a warning means.
