Abstract
A low profile and light weight keyboard for portable electronic devices, such as notebook computers. In specific embodiments, the present invention provides a low profile keyboard 218 where the keycap engaging members 202 extend unobstructed below the back plate or circuit board 204. The travel of the key below the back plate may be eliminated from the overall stowed keyboard thickness by popping up the keyboard or otherwise extending the keyboard to a deployed position having sufficient thickness to accommodate the travel of the engaging members 212 below the base 204.
