abstract = {A novel test facility for the efficient evaluation of
microelectromechanical system ( MEMS) switches and the
development of alternative contact materials is described.
The facility utilizes the upper cantilever from commercial
MEMS contact switches, and tests these against alternative
bottom contact materials within a modified atomic force
microscope ( AFM). The test closely approximates the real
switch, but can accommodate a wider range of test conditions
and contact materials. The facility allows alternative
contact materials to be easily and quickly incorporated, and
therefore evaluated by measuring the number of cycles to
failure. The evolution of the wear surfaces of the switch
contact materials under test can also be easily examined. In
order to demonstrate the facility, the evolution of the
contact resistance and wear of a commercial RF MEMS
cantilever with Au contacts was monitored under accelerated
test conditions, comparing the behavior of Au bottom
contacts to an alternative Au-Ni alloy contact material. The
Au-Ni( 20 $at.\%)$ alloy displayed reduced wear rates and
improved switch cycle lifetimes compared to pure Au, while
retaining acceptable values of contact resistance.},
