Double-sided keyboard having two keymats and one activation mat

A method of producing a double-sided keyboard for entering information in an electronic device, comprising the steps of:

• providing a circuit board having a first side and an opposing second side with electrically conductive segments on the first side;
• providing an activation mat adjacent to the first side of the circuit board, the activation mat having a plurality of electrically conductive sections facing the electrically conductive segments on the first side of the circuit board;
• providing a first keymat adjacent the activation mat further from the first side of the circuit board, the first keymat having a plurality of the first keys;
• and
• providing a second keymat adjacent to the second side of the circuit board, the second keymat having a plurality of second keys, so as to allow the first and second keymats to activate the circuit board by pressing at least one of the first and second keys, thereby causing at least one of the electrically conductive sections on the activation mat facing the electrically conductive segments on the first side of the circuit board to make electrical contact only with part of the electrically conductive segments on the first side of the circuit board for providing a signal indicative of the information for use in the electronic device.

A method of entering and using information in an electronic device, comprising the steps of:

• pressing at least one of a first plurality of keys of a first keymat situated adjacent to a first side of an activation mat having a plurality of electrically conductive sections in order to cause at least one of the electrically conductive sections of the activation mat to operatively connect to a circuit board having a first side and an opposing second side, wherein the first side of the circuit board is situated adjacent a second side of the activation mat opposing the first side thereof, for providing a first signal, or
• pressing at least one of a second plurality of keys situated adjacent to the second side of the circuit board in order to cause at least one electrically conductive section of the activation mat to operatively connect to the first side of the circuit board, for providing a second signal;
• and
• using either the first signal or the second signal for performing a function related thereof in the electronic device.
