A persistent current switch (PCS) is used for superconducting applications, such as superconducting magnetic energy storage (SMES) system. We have proposed a mechanical switch of high-temperature superconductor (HTS) as a mechanical PCS. In the previous paper, the sample surfaces were carefully polished and deposited with metals. As a result, the transfer current exceeded 30A, and the contact resistance reduced to 6μΩ at constant load 500N. In this paper, the experiment result when depositing metal thickly, and the relation between contact resistance and load were reported. Reduction of contact resistance and load was tried by depositing metals. Consequently, contact resistance was able to be reduced. When depositing indium, the increase of contact resistance by load reduction was able to be suppressed. Additionally, based on the experimental results and surface observation, we analyzed the current density and temperature distribution of the switch with finite element method (FEM). This analysis result may lead to the elucidation of a contact mechanism.
