The second connecting portion 34 and the second pressing portion 20 b are pressed by rotating the slider 161 after the connection object 40 is inserted, in the same manner as in the operation mode of the first contact 14 by rotating the slider 16. When the portion 36 rotates, the second pressing portion 20 b is pushed up by the pressing portion 36 in a direction away from the substrate mounting surface, so that the second contact portion 22 b presses and contacts the connection object 40. The size and shape of the second connecting portion 34 b and the second pressing portion 20 b are appropriately designed in order to form a configuration showing such an operation mode .

Further, since a protruding portion 26 is provided at the tip of the second pressing portion 20 of the second contact 142 and the repulsive force against the rotation of the slider 161 is strong when the pressing portion 36 of the slider 161 is rotated, the slider 161 is arranged. It is desirable to prevent the central portion in the pitch direction from bulging in the direction of the arrow “C” in FIG. 6 (B), but considering the strength of the slider 161 due to the narrowing of the pitch, there are two types of contacts 14 , 142 , it is sufficient if it is provided in one of the contacts 14. The size of the protruding portion 26 may be any size as long as it can play such a role, and is appropriately designed so that the pressing portion 36 of the slider 161 is caught.
