Summary :

Holographic pattern measuring system (HPMS) which has been developed by the authors as applied to measure a thermal deformation of contact spring due to current flow. As the results of investigations, a microscopical rolling of contact point was clarified and a relationship between the changing spring shape and the contact voltage was qualitatively mode clear.
