Abstract:
A control device with a snap function, including a support, a push-button mounted so as to move on the support so as to have a travel in translation along an axis (A-A), and a spring element able to exert a reactive force on said push-button, said reactive force passing through a maximum-during the travel of the push-button, wherein said spring element includes a sheet made of resilient material, inserted between said push-button and said support and having at least a median zone arranged in its central portion and at least a pair of support zones located at the ends of said sheet, said pair of support zones and said median zone being intended to abut one against said push-button and the other against said support so that the travel of said push-button tends to bend said sheet along a longitudinal axis (B-B), and wherein said sheet has a bent or V-shaped cross section in a rest position of said spring element.
