Abstract
A micro-magnetic switch includes a permanent magnet and a supporting device having contacts coupled thereto and an embedded coil. The supporting device can be positioned proximate to the magnet. The switch also includes a cantilever coupled at a central point to the supporting device. The cantilever has a conducting material coupled proximate an end and on a side of the cantilever facing the supporting device and having a soft magnetic material coupled thereto. During thermal cycling the cantilever can freely expand based on being coupled at a central point to the supporting device, which substantially reduces coefficient of thermal expansion differences between the cantilever and the supporting device.
