wherein the body of the at least one double key pivots about the first external contact portion when the second external contact portion moves to thereby actuate the second switch, and the body of the at least one double key pivots about the second external contact portion when the first external contact portion moves to thereby actuate the first switch.

2. The key assembly of claim 1 , wherein the first external contact portion includes at least one of a text character and a functional character and the second external contact portion includes at least one of a text character and a functional character.

3. The key assembly of claim 1 , further comprising a deflection web support engaging the deflection web and disposed between the deflection web and the at least one pair of switches.

4. The key assembly of claim 3 , wherein the deflection web support includes at least one leg disposed between the first actuator and the second actuator.

5. The key assembly of claim 1 , wherein the keypad layout is one of a QWERTY-type keypad layout, a QWERTZ-type keypad layout, an AZERTY-type keypad layout, and a DVORAK-type keypad layout.

6. The key assembly of claim 1 , wherein the first external contact portion includes a first post, the first post contacting the first actuator, and the second external contact portion includes a second post, the second post contacting the second actuator.

7. The key assembly of claim 1 , wherein the first external contact portion includes a concave contact surface, and the second external contact portion includes a concave contact surface.

8. A key assembly for an electronic device, the key assembly comprising:

a base;

a plurality of switches supported by the base;

a plurality of keys including:

a first set of double keys arranged in five columns with three rows;

a second set of keys arranged in three columns with one row, the second set of keys including double keys and a space key;

each of the double keys being movably supported by the base and including a body having:

a first external contact portion being movable to actuate a first switch of the plurality of switches;

a second external contact portion being movable to actuate a second switch of the plurality of switches;

wherein the body of each double key pivots about the first external contact portion when the second external contact portion moves toward and actuates the second switch, and the body of each double key pivots about the second external contact portion when the first external contact portion moves toward and actuates the first switch; and

a deflection web disposed between the plurality of keys and the plurality of switches, the deflection web including a plurality of pairs of actuators, and each pair of actuators supports one of the double keys.

9. The key assembly of claim 8 , wherein each first external contact portion includes at least one of a text character and a functional character and each second external contact portion includes at least one of a text character and a functional character.

10. The key assembly of claim 8 , wherein the first external contact portion of each double key is movable toward the plurality of switches to move a first actuator of one of the pairs of actuators and thereby actuate the first switch, and the second external contact portion of each double key is movable toward the plurality of switches to move a second actuator of the one of the pairs of actuators and thereby actuate the second switch.

11. A key assembly for an electronic device, the key assembly comprising:

a base supporting a plurality of switches;

a plurality of keys supported by the base, the plurality of keys including:

a first set of double keys arranged in five columns with three rows;

a second set of keys arranged in three columns with one row, the second set of keys including double keys and a space key;

each of the double keys being movably supported by the base and including a body having:

a first external contact portion being movable to actuate a first switch of the plurality of switches;

a second external contact portion being movable to actuate a second switch of the plurality of switches;

wherein the body of each double key pivots about the first external contact portion when the second external contact portion moves toward and actuates the second switch, and the body of each double key pivots about the second external contact portion when the first external contact portion moves toward and actuates the first switch.

12. The key assembly of claim 11 , further comprising a deflection web disposed between the plurality of keys and the plurality of switches.

13. The key assembly of claim 12 , further comprising a deflection web support disposed between the deflection web and the plurality of switches, the deflection web support including a plurality of legs, each of the plurality of legs being disposed between adjacent actuators of the deflection web.
