Abstract
Improved switch device, essentially characterized by comprising a housing and a box of mechanisms linked together, comprising in the housing an exit window of the powered swinging lever, whose axes rotate on entrants opposite on both sides of the window, where they are maintained by a helical expansion spring housed in the central part of the lever, which spring has its lower end supported on the central part of a T-piece, at the end of which are the contacts capable of supporting the respective fixed terminals in the bottom of the box, which in the middle part of the bottom presents an input terminal with supports for the central part of the T-piece, which is tilted on these supports, presenting by effect of the spring two positions of stable equilibrium, corresponding to the supports on the extreme terminals.
