Abstract
A pressing device includes a base board, an upper board unit that is disposed over the base board, and an intermediate unit that is disposed between the base board and the upper board unit. The upper board unit includes a panel, a circuit board, and a tact switch. The intermediate unit includes a middle portion that corresponds in position to the tact switch, a surrounding frame member, and a plurality of interconnecting board members. When the upper board unit is pressed, at least one of the interconnecting board members is deformed, and the middle portion is driven to convert the tact switch from an initial state to a triggered state.
