Movable contact point, switch with movable contact point, and embossed tape for containing movable contact point

A movable contact comprising a conductive member having an outer end having substantially a rectangular shape when viewed from the conductive member, wherein

• the conductive member includes:
• a dome portion having an upper surface which is convex upward, a lower surface which is concave upward, and an outer border;
• a flange having an outer border and an inner border which is connected to the outer border of the dome portion, the flange extending from the inner border of the flange to the outer border of the flange in a direction away from the dome portion when viewed from above the conductive member;
• connection portions provided at four corners of the rectangular shape of the conductive member, respectively, each of the connection portions having a lower border and an upper border which is connected to the outer border of the flange, the each of the connection portions protruding downward from the upper border of the each of the connection portions to the lower border of the each of the connection portions;
• and
• contact portions, respective one of the contact portions having an outer border and an inner border which is connected to the lower border of the each of the connection portions, the respective one of the contact portions extending from the inner border of the respective one of the contact portions to the outer border of the respective one of the contact portions away from the flange when viewed from above the conductive member, and
• a first boundary portion where the each of the connection portions is connected to the flange is curved to be concave toward the dome portion when viewed from above the conductive member, and
• a second boundary portion where the each of the connection portions is connected to the respective one of the contact portions is curved to be concave toward the dome portion when viewed from above the conductive member.

An embossed tape configured to accommodate a movable contact therein, the embossed tape comprising a base tape having an upper surface having an accommodation recess portion provided therein, the accommodation recess portion being configured to accommodate the movable contact therein, wherein

• the movable contact includes:
• a conductive member having an outer end having substantially a rectangular shape when viewed from above the conductive member;
• an extension portion protruding from the conductive member;
• and
• a mounting portion connected to the extension portion,
• the conductive member includes:
• a dome portion having an upper surface which is convex upward, a lower surface which is concave upward, and an outer border;
• a flange having an outer border and an inner border which is connected to the outer border of the dome portion, the flange extending from the inner border of the flange to the outer border of the flange in a direction away from the dome portion when viewed from above the conductive member;
• connection portions provided at four corners of the rectangular shape of the conductive member, respectively, each of the connection portions having a lower border and an upper border which is connected to the outer border of the flange, the each of the connection portions protruding downward from the upper border of the each of the connection portions to the lower border of the each of the connection portions;
• and
• contact portions, respective one of the contact portions having an outer border and an inner border which is connected to the lower border of the each of the connection portion, the respective one of the contact portions extending from the inner border of the respective one of the contact portions to the outer border of the respective one of the contact portions away from the flange when viewed from above the conductive member,
• the accommodation recess portion includes:
• a first recess portion having a first bottom surface and a first side wall connected to the first bottom surface, the first recess portion being configured to accommodate the flange of the movable contact therein;
• a receiving portion provided on the first bottom surface of the first recess portion, the receiving portion being configured to receive a lower surface of the flange of the movable contact thereon;
• a second recess portion having a second bottom surface and a second side wall connected to the second bottom surface, the second recess portion being connected to the first recess portion, the second recess portion being configured to accommodate the extension portion and the mounting portion of the movable contact therein;
• and
• regulator portions provided on the first side wall of the first recess portion, respective one of the regulator portions being configured to regulate a position of the respective one of the contact portions of the movable contact, and
• a gap between the respective one of the contact portions and the respective one of the regulator portions is smaller than a gap between the extension portion and the second side wall of the second recess portion and a gap between the mounting portion and the second side wall of the second recess portion.
