Abstract
A safety switch includes an activation key housed in a casing, a pair of contact-holding elements, and a triad of electric terminals. The contact-holding elements oscillate between a passive position and an active position, the positions being imposed by a corresponding position of the activation key. The contact-holding elements are mutually electrically connected through conductive elements that, when operation of the switch takes place in a condition of failure, can move with respect to one another for relative displacement of mating surfaces to determine a loss of contact between the contact-holding elements.
