In the 1711M mechanism of -d', since the entire surface between the contacts is wetted with the conductive liquid 9, it is difficult for the conductive liquid 9 to dissolve and bridge, so it is necessary to widen the gap between the contacts. In particular, when the mounting direction is such that the contact part of the movable lead 5 faces downward as shown in FIG. Sufficient contact clearance was required to ensure reliable bridging characteristics.

量が増えることはない。By doing this, even if the contact portion of the movable lead 5 comes into contact with the contact point 2 of the fixed lead 1, the contact area becomes small, making it easier for the conductive liquid 9 to dissolve and bridge, thereby narrowing the contact gap D1. becomes possible. Further, the opposing surfaces of the comb teeth are coated with a metal 5d that is easily wetted by the conductive liquid 9, and the surface of the comb 6F35a (excluding the comb tooth gap 5c) is coated with a metal 5b that is not wetted by the conductive liquid 9. According to
The conductive liquid 9 does not spread beyond the comb tooth gap 5c, and even if the contact portion of the movable lead 5 is placed downward, the amount of conductive liquid 9 retained at the contact portion does not increase.
