Patent ID: 7755899

Claim:
A high conductivity switch comprising: a sealed cavity with a first wall and a second wall, wherein at least the second wall is a membrane assembly, the second wall being adapted to be arranged with a gap to a receiving structure; a thermal actuator material filling a portion of the sealed cavity, the thermal actuator material being adapted to change volume with temperature at least partly due to a phase change of the thermal actuator material at a predefined temperature or temperature interval; and a conductor material filling a portion of the sealed cavity, wherein the conductor material provides a high conductivity transfer structure between the first wall and the second wall, and the conductor material is in liquid phase at least at a predefined temperature or temperature interval; whereby, in use, the thermal actuator material is arranged to upon a temperature induced volume change obtained at the predefined temperature or temperature interval, displace, the second wall, so that the gap to the receiving structure can be bridged.
