Abstract

A novel type of single use bi-stable MEMS solid off-on switch based on metal bridge igniter is described and its performance test results are presented. The switch mechanically connects a couple of comb electrodes which belong separately to different metallic lines. Switching between the two stable states (off and on) is accomplished by a voltage pulse supplied by an energy storage capacitance through a metal bridge igniter above the electrical lines to be connected. The switch can be driven by external signal and its predicted lifetime is very long, therefore the switch can be used for long term store systems.
