Abstract: An electric switch having a body (1) of insulating material which contains at least one recess (2) into which enter the ends (3a, 4a) of at least two terminals (3,4) the opposite ends of which (3b,4b) project outside the body, and a switch mechanism comprising an electrically-conducting element (5) fitted so as to slide in the recess (2) between first and second stable positions. The switch is characterized in that the electrically-conducting element (5) comprises a stirrup having an elastic middle part (6), contact points (8) and upwardly extending arms (9) that extend towards the opening (10) of the recess (2), appearing in windows (15) defined in the opening (10) on either side of an insulating element (14) that retains the stirrup (5) in the recess (2), the arms (9) constituting structure for moving the stirrup (5) between first and second positions.
