Multiple position electrical switch

An electrical switch comprising:

• a casing made of insulating material;
• a fixed upper contact and a fixed lower contact which are vertically opposed;
• a mobile contact blade which is elastically deformable between two switching states in each of which a contact part of the mobile contact blade is in electrical contact with the fixed lower contact or with the fixed upper contact respectively;
• a fixed support which bears the mobile contact blade and which comprises a vertical front support branch and a vertical rear support branch which are spaced apart longitudinally and each of which comprises a transversely oriented horizontal notch respectively a front and rear notch, in the bottom of which is housed a transverse free edge of a respectively front and rear section of the mobile contact blade;
• and actuator which collaborate with a part of the mobile contact blade to bring about a change in switching state;
• wherein the fixed support comprises two parallel vertical support plates spaced transversely apart and of which each comprises a vertical front support branch and a vertical rear support branch which are spaced apart longitudinally and of which each comprises a transversely oriented respectively front and rear horizontal notch in the bottom of which is housed a portion of the said transverse free edge of a respectively front and rear section of the mobile contact blade.
