Trigger level push button for use in case of watch, has rod integrated with head, and elastic element applying stress having radial component on rod when button is actuated, for defining trigger level
The button (1) has a rod (6) integrated with a head (2), and transmitting force to an inner side of a timepiece case. The rod co-operates with an elastic element (24) i.e. spiral curved flat spring, after a first partial stroke, for defining a trigger level with reference to the force, beyond which the button realizes a second partial stroke above the trigger level. The elastic element applies stress having a radial component on the rod when the button is actuated, for defining the trigger level. A cylindrical rod portion (9) is arranged in contact with the elastic element through a ball (22).
