Abstract
In a method for forming a micromechanical device, a force associated with operation of the device is varied between locations spaced across a conductive element of the device. The method may be used to form a switch adapted such that a force associated with actuation of the switch varies between locations spaced across a contact element of the switch. The varied force may include a required closing force for the switch, an applied force during actuation of the switch, a restoring force tending to open the switch, and/or a sticking force tending to keep the switch closed. A variable-valued circuit element having a conductive element and conductive pad may also be formed, adapted such that a fraction of the conductive element which is moved to the proximity of the conductive pad is variable depending on a total magnitude of a force applied.
