Abstract

A multiple position switch having a plurality of contact regions on, e.g., a PCB and corresponding conductive regions mounted on a piece of resilient material resting on the surface, with each conductive region contained within a hollowed portion of the resilient material to be thereby spaced apart from the respective contact region, and having a swivelingly mounted joystick, the joystick having a plurality of urging members positioned radically outward from the longitudinal axis of the joystick corresponding in number and position to the number and position of the respective contact regions. Also disclosed are separate embodiments in which the conductive regions are, on the one hand, electrically insulated from each other and the respective contact regions are formed by pairs of contacts between which electrical contact is to be made, and, on the other hand, electrically connected to each other and a common, with the contact regions formed of a single contact to which electrical connection with the common is desired to be made. Also, alternative embodiments of the joystick are disclosed wherein the urging members form protrusions either from a plurality of radically extending legs or a plurality of triangular segments forming a poly-sided disc.

Claims

1. A multiposition switch comprising:

a surface;

a plurality of contact regions on the surface each formed by a pair of first and second adjacent contacts of an electrical switch, one of which being a resilient member, said contacts being spaced apart and electrically insulated one from the other with said resilient member having an indented surface thereon which is spaced apart from the contact regions, and an electrical conductor in electrical contact with a common point for each of the electrical switches formed by the respective contact regions;

said plurality of conductive regions each being located within a separate hollow formed concentrically in the resilient material and thereby spaced apart from the surface, with the conductive region formed in a protrusion within each hollow;

a joy stick mounted in swiveling relation to the surface and having a manipulating rod and a plurality of urging members disposed radially outward from the longitudinal axis of the manipulating rod at generally the swivelingly mounted end of the joy stick, and corresponding in number and position to the number and position of the respective contact regions;

said joy stick, upon being actuated to depress the resilient member, moving at least one of the urging members towards the stationary contact regions, with the urging member aligned with a conductive region bringing this conductive region into contact with an aligned stationary contact region; and

the resilient member forming a donut shape about the swivelingly mounted end of the joy stick, with a hub of rigid material located at the center of the donut shaped resilient member and having formed thereon a swivel mounting surface for the swiveling mounting of the joy stick, said hub forming the electrical conductor in the resilient member.

2. The switch of claim 1 further comprising:

a plurality of legs extending radially outward from the longitudinal axis of the manipulating rod at generally the swivelingly mounted end of the joy stick, each leg having at the terminal end thereof a respective urging member.

3. The switch of claim 2 further comprising:

a hub of rigid material located at the center of the donut shaped resilient member and having formed thereon a swivel mounting surface for the swiveling mounting of the joy stick.

4. The switch of claims 2 or 3 further comprising:

the urging members being formed by a protuberance at the terminal end of each leg and extending toward contacting relation with the resilient member.

5. The switch of claim 1 further comprising:

a plurality of segments extending radially outward from the longitudinal axis of the manipulating rod at generally the swivelingly mounted end of the joy stick, each segment joined with its adjacent segments and having disposed thereon an urging member in contacting relation to the resilient member.

6. The switch of claim 5 further comprising:

the plurality of segments forming a polysided disc-shaped member with the urging members forming protuberances extending toward contacting relation to the resilient member.
