ABSTRACT:
An electrical switch system may include a contact-bearing support configured to delimit a recess in a substantially horizontal bottom, wherein at least two fixed electrical contacts are positioned in the recess. Additionally, the electrical switch system may include at least one dome-shaped first triggering device configured to be elastically deformable from a top rest position to form an electrical link between the at least two fixed electrical contacts. The electrical switch system may also include an actuating push-button mounted to be displaced substantially vertically downward relative to the support. Further, the electrical switch system may include a mechanism configured to return the push-button to the rest position and an elastic element configured to exert an elastic force on the push-button, wherein the elastic force is directed upward when the push-button is displaced downward beyond a contact position.
