Abstract

A keyswitch structure includes a base plate, a keycap, and two supports connected to the base plate and the keycap. The keycap is movable relative to the base plate through the two supports. The support is pivotally connected to the base plate through a pivotal connection structure that includes a guiding slot and a protruding shaft oppositely disposed on the support and the base plate. The guiding slot has an opening and an indentation portion. The opening is located at an upper end of the guiding slot. The protruding shaft enters the guiding slot from the opening to rotatably fit in the indentation portion, so that the support is pivotally connected to the base plate.
