A conventional sliding contact device consisting of a sliding contact having a contact material of 30 wt% A g -P d facing a thick film conductor pattern of 30 wt % A g -P d on a wiring board was subjected to sliding opening and closing under the following test conditions.

~50wt% Since the contact material has a soft hardness and is slippery, it does not damage the opposing Ag-Pt thick film conductor pattern 3, and does not adhere or peel off, reducing wear. This is because the contact material containing 10 to 50 wt% of -Mo has good electrical conductivity and does not generate heat.

1. When the sliding contact 5 comes into contact with the A1zO's board and becomes open (infinite contact resistance). The judgment was made based on the case where a short circuit occurred due to clogging of the slit between the thick film conductor patterns 3.

も良い。Although the wiring board 4 of the sliding contact device in the above embodiment is circular, it may also be rectangular. In that case, the thick film resistor pattern is preferably formed on one side end of the rectangular wiring board, and the thick film conductor patterns are preferably connected to the thick film resistor pattern and formed in parallel at regular intervals in the longitudinal direction thereof. The shear contact is slidable in the longitudinal direction of the thick film resistor pattern, facing the thick film conductor pattern. In addition, a thick film resistor pattern is formed on a ceramic substrate in a bellows shape and reciprocated back and forth, and a wiring board is formed on which thick film conductor patterns are arranged at regular intervals, and the wiring board faces the thick film conductor pattern. It is also possible to use a sliding contact device consisting of a sliding contact that is slidable.
