Multi-directional operating switch and multi-directional operating device using the same
First Claim
1. A multi-directional operating switch comprising:
- a case having an opening in an upper surface thereof, said case including a central contact, an outer contact disposed in a position spaced away from said central contact, and a plurality of peripheral contacts, all disposed on a bottom surface of said opening;
a dome-like circular movable contact having a center portion disposed above said central contact, and a lower peripheral rim of said dome-like circular movable contact resting in contact with said outer contact;
a cover having with a through hole in a location concentric to said dome-like circular movable contact; and
a manipulation body comprising a shaft protruding said through hole, a flange having electrical conductivity on at least a lower surface thereof, said flange disposed at a lower end of said shaft, and a projection extending from the lower surface of said flange, said shaft being both tiltable and movable in a vertical direction, and said manipulation body biased upwardly by said dome-like circular movable contact in a manner that at least a peripheral surface of said flange is in contact with a lower surface of said cover, wherein said projection on said flange depresses and deforms said dome-like circular movable contact to establish a first electrical continuity between said central contact and said outer contact, when said shaft being moved in a downward direction, and the lower surface of said flange establishes a second electrical continuity between adjacent two of said plurality of peripheral contacts responsive to said shaft being moved in a tilting direction.

Abstract
A multi-directional operating switch comprises: a case made of resin having generally a square opening on top, provided on a bottom surface thereof with a central contact, an outer contact, and peripheral contacts disposed at each corner of the opening; a dome-like circular movable contact disposed within the opening in a manner to rest in contact with the outer contact; a manipulation body having a flange and a contact plate under the flange, placed above the dome-like circular movable contact; and a cover for covering the opening and having a shaft of the manipulation body penetrating therethrough. Switching operation is made between the central contact and the outer contact when the shaft is depressed, and between any adjacent pair of the peripheral contacts, as the dome-like circular movable contact is being deformed, when the shaft is tilted.

-
a case having an opening in an upper surface thereof, said case including a central contact, an outer contact disposed in a position spaced away from said central contact, and a plurality of peripheral contacts, all disposed on a bottom surface of said opening;
a dome-like circular movable contact having a center portion disposed above said central contact, and a lower peripheral rim of said dome-like circular movable contact resting in contact with said outer contact;
a cover having with a through hole in a location concentric to said dome-like circular movable contact; and
a manipulation body comprising a shaft protruding said through hole, a flange having electrical conductivity on at least a lower surface thereof, said flange disposed at a lower end of said shaft, and a projection extending from the lower surface of said flange, said shaft being both tiltable and movable in a vertical direction, and said manipulation body biased upwardly by said dome-like circular movable contact in a manner that at least a peripheral surface of said flange is in contact with a lower surface of said cover, wherein said projection on said flange depresses and deforms said dome-like circular movable contact to establish a first electrical continuity between said central contact and said outer contact, when said shaft being moved in a downward direction, and the lower surface of said flange establishes a second electrical continuity between adjacent two of said plurality of peripheral contacts responsive to said shaft being moved in a tilting direction. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
detecting an ON state between an adjacent pair of said plurality of peripheral contacts responsive to said shaft of said manipulation body being tilted, for selecting an item among a plurality of items; and
detecting an ON state between said central contact and said outer contact responsive to said shaft being depressed vertically downward, for entering said item selected among said plurality of items.
-
-
14. The multi-directional operating device according to claim 13, wherein said device detects sequential switching signals transmitted from said central contact and said outer contact produced when said shaft is continuously depressed vertically for a plurality of times within a predetermined period of time, for executing a plurality of predetermined commands in a sequential order by said signals.
-
15. The multi-directional operating device according to claim 13, wherein said device executes a command pre-allocated to each of tilting directions of said shaft, when said shaft is tilted in directions opposite to each other with respect to a neutral position of said shaft.
-
16. The multi-directional operating device according to claim 13, wherein said device detects an ON state between said central contact and said outer contact when said shaft is depressed vertically downward, and switches a command pre-allocated to each of respective tilting directions of said shaft in a predetermined order.
-
17. A multi-directional operating device provided with the multi-directional operating switch of claim 1, wherein said device is for:
-
detecting an ON state between an adjacent pair of said plurality of peripheral contacts responsive to said shaft of said manipulation body being tilted, for selecting one of a plurality of signals whereto directions of a vector are pre-allocated, for moving a displayed object toward a direction of said vector corresponding to a selected signal; and
detecting an ON state between said central contact and said outer contact responsive to said shaft being depressed vertically downward, for executing a command allocated in advance to said moved object.
-
-
18. The multi-directional operating device according to claim 17, wherein said device detects sequential switching signals transmitted from said central contact and said outer contact produced when said shaft is continuously depressed vertically for a plurality of times within a predetermined period of time, for executing a plurality of predetermined commands in a sequential order by said signals.
-
19. The multi-directional operating device according to claim 17, wherein said device executes a command pre-allocated to each of tilting directions of said shaft, when said shaft is tilted in directions opposite to each other with respect to a neutral position of said shaft.
-
20. The multi-directional operating device according to claim 17, wherein said device detects an ON state between said central contact and said outer contact when said shaft is depressed vertically downward, and switches a command pre-allocated to each of respective tilting directions of said shaft in a predetermined order.
