Abstract: A force sensing device operable as a pressure switch or other triggering device or regulator includes a mechanical amplifier and deamplifier which translates motion created by changes in the applied force into larger or smaller movements for operating an output indicator or switch. An actuator arm mounted on a movable fulcrum translates motion induced by the applied force to the output indicator or switch, which responds to motion of the actuator arm in a manner determined by the position of the fulcrum. When employed as a pressure switch, for example, the shiftable fulcrum permits adjustment of the ''''deadband'''' of the switch, while other adjustments determine the position of the deadband on a pressure scale. The device is operable as a differential pressure switch or as a temperature regulator as well.
