Abstract
Multifunction key switch in which a multifunction key 6 is fitted into a hole 4 formed in a front case 3 so as to be able to pivotally move in a thicknesswise direction of the front case 3, as well as to enter a plurality of different operation instructions. A hole 8 is formed so as to penetrate through the multifunction key actuation section 6 in the thicknesswise direction of the front case 3. An execution key actuation section 7 is fitted into the hole 8 and determines the operation instruction entered by way of the multifunction key actuation section 6 when being pressed in the thicknesswise direction of the front case 3.
Claims6
A multifunction key for use with a portable device comprising:
- a case having a hole formed therein;
- a multifunction key actuation section which is fitted into the hole and is pivotally movable in a thicknesswise direction of the case, to input a plurality of different operation instructions;
- another hole formed so as to penetrate through the multifunction key actuation section in the thicknesswise direction of the case;
- an execution key actuation section which is fitted into the latter hole and determines the operation instruction entered by way of the multifunction key actuation section when being pressed in the thicknesswise direction of the case;
- and
- wherein projecting faulty-operation prevention members are formed at respective areas where support pins for pivotally supporting the multifunction key actuation section are provided, and when the execution key actuation section is pressed in the thicknesswise direction of the case, the faulty-operation prevention members prevent the multifunction key actuation section from being pressed in the thicknesswise direction of the case.

- another hole formed so as to penetrate through the multifunction key actuation section in the thicknesswise direction of the case;
- an execution key actuation section which is fitted into the latter hole and determines the operation instruction entered by way of the multifunction key actuation section when being pressed in the thicknesswise direction of the case;
- and
- wherein pressing force required for actuation of a metal dome by way of a rubber key when the execution key actuation section is pressed in the thicknesswise direction of the case is set so as to become greater then pressing force required for actuation of metal domes by way of the rubber key when the multifunction key actuation section is pressed in the thicknesswise direction of the case.
