Abstract
A mechanical load bearing indicator producing signals to a user when the user applies more than selected amounts of load between an extremity of the use and a surface. The indicator has a base plate adapted to establish a frame of reference with the surface, a load plate mounted for movement toward and away from the base plate and adapted to receive loads from the user's extremity, and at least two snap domes mechanically engaged between the base plate and the load plate for generating two signals when more than two different respective loads are applied to the load plate by the extremity. The domes are either in series between the plates or are together in a dual dome containing both, or are one or more stacks of domes which individually collapse under incremental loads which are added together to form the selected lower and higher loads.
