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.

A controller and methods for controlling a retractable keyboard are disclosed. The controller may control and monitor an extend operation of the retractable keyboard using a first pin, and control and monitor a retract operation of the retractable keyboard using a second pin. Open drain signaling may be used on the pins to allow control and monitoring through the same pin. To control and monitor the extend (or retract) operation using a single pin, the controller releases the voltage at the pin to a floating high state to activate the muscle wire to extend (or retract) the keyboard. During the operation, the controller checks the voltage state at the pin. If the voltage at the pin has been pulled to low by the closing of a limit switch, the controller determines that the extend (or retract) operation has completed and in response drives the pin to a low voltage state to deactivate the muscle wire.
