Abstract
A keyboard includes a plurality of key modules. Each key module includes a baseplate, a circuit membrane disposed on the baseplate, a metal dome disposed on the circuit membrane, an elastic member disposed on the metal dome, and a keycap. The elastic member and the linkage member are configured to be a movable switch mechanism. The circuit membrane has a conductive circuit. The metal dome has an opening corresponding to the conductive circuit of the circuit membrane. A trigger portion protrudes from an underside of the elastic member. When the keycap is pressed, the trigger portion passes through the opening of the metal dome, and moves downwards to abut against the conductive circuit to induce a conducting signal. The movable switch mechanism can be made by a double injection molding method.
