A Microelectromechanical (MEMS) device that can minimize the effects of fabrication tolerances on the operation of the device can include a MEMS electromagnetic actuator to selectively generate displacement forces to displace an actuable element along a path. A cantilever can apply an opposing force to the actuable element to control the amount of displacement. Coil ends of the actuator can be shaped to vary a gap distance between the coil ends, and/or the magnetic portion of the actuable element may be shaped, so as to vary the force applied to the actuable element along the displacement axis. One or more pins located in the deflection path of the cantilever can contact the cantilever at one or more points so as to change the bending resistance of the cantilever. The cross-section of the cantilever can also be varied along its length so as to change the bending resistance of the cantilever.
