Multiple position electrical switch

An electrical switch comprising:

• a casing made of insulating material;
• a fixed upper contact and a fixed lower contact, wherein the fixed upper contact and the fixed lower contact are vertically opposed;
• a mobile contact blade, wherein the mobile contact blade is elastically deformable between two switching states such that 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 bearing the mobile contact blade, wherein the fixed support comprises two parallel vertical support plates spaced transversely apart from one another, further wherein each vertical support plate comprises a vertical front support branch and a vertical rear support branch spaced apart longitudinally from one another, and further wherein each of the vertical front support branch and the vertical rear support branch comprises a transversely oriented horizontal notch, in the bottom of which is housed a transverse free edge of a respective front and rear section of the mobile contact blade;
• and
• an actuator, wherein the actuator collaborates with a part of the mobile contact blade to bring about a change in switching state.
