Abstract

A control pod for a vehicle is structured and positioned to provide easy manual access to the actuators for pairs of functionally-related mechanical switches housed in the control pod. Integrally-formed pairs of actuators are associated with respective pairs of functionally-related switches. Each switch of a pair is mounted on an opposite side of a circuit board from the other switch. The circuit board is mounted in a control pod housing, and the pairs of actuators are connected to the circuit board. Each actuator of a pair extends to an opposite side of the circuit board for actuation of the respective switch. A pair of actuators are joined at a common midsection and are resiliently deformable about that midsection to provide the displacement required for switch actuation. Pairs of visual indicators are positioned on the control pod in proximity with a respective pair of actuators for signifying actuation of respectiive ones of an associated pair of switches.

Claims

1. A control pod for use in vehicles comprising, in combination:

a hollow pod housing including a control-input portion, said housing being adapted for cantilevered mounting in the vehicle such that said control-input portion thereof is positioned for easy access by one hand of an operator;

at least one pair of functionally-related switches mounted interiorly of said housing, each said switch being responsive to a respective mechanical input stimulus to effect switch actuation;

at least one pair of manually-operated switch actuators, said pair of actuators being mounted in said housing and being configured and positioned such that a respective said actuator is associated with a respective said switch and includes a respective tactile region and a switch-contacting portion; and

each said pair of actuator tactile input regions being located at the control-input portion of said housing and positioned for readily accessible, manually-complemental operation by one hand of an operator.

2. The control pod of claim 1 including plural pairs of said functionally-related switches mounted in said housing and a corresponding plurality of said pair of switch actuators, each said pair of switch actuators being associated with a respective pair of said switches and said pairs of switch actuators in said plurality being arrayed in alignment.

3. The control pod of claim 2 wherein said pod housing is contoured in said control-input portion to define an external surface facing in at least two different directions and wherein each actuator tactile input region of a respective said pair is positioned such that it faces substantially in a respective one of said two different directions thereby to facilitate separation and tactile identification of each tactile input region of a respective pair.

4. The control pod of claim 1 wherein said pair of switch actuators is of integral construction.

5. The control pod of claim 2 wherein the two switch actuators in a said pair thereof are integrally joined.

6. The control pod of claim 5 wherein all of said pairs of switch actuators in said plurality are integrally joined to one another.

7. The control pod of claim 4 wherein each said pair of switch actuators comprises a respective pair of tactile input members extending in generally opposite directions from a common, transversely-extending midsection, a respective said switch contact portion being integrally formed on each said tactile input member, said actuator midsection being mounted in said housing in such manner as to resist rotation of said input members about an axis extending transversely of said input member at said midsection, and said input members each being independently, resiliently deflectable about said actuator midsection from a rest position to move a respective said switch-contacting portion into actuating engagement with a respective said switch.

8. The control pod of claim 7 wherein each said switch-contacting portion comprises a projection extending inwardly from a respective tactile input member.

9. The control pod of claim 6 wherein each said pair of switch actuators comprises a respective pair of tactile input members extending in generally opposite directions from a common, transversely-extending midsection, a respective said switch contact portion being integrally formed on each said tactile input member, said actuator midsection being mounted in said housing in such manner as to resist rotation of said input members about an axis extending transversely of said input member at said midsection, and said input members each being independently, resiliently deflectable about said actuator midsection from a rest position to move a respective said switch-contacting portion into actuating engagement with a respective said switch.

10. The control pod of claim 9 wherein said pairs of switch actuators are joined by a common spine formed integrally therewith and extending transversely thereof along the midsections of the respective pairs of switch actuators.

11. The control pod of claim 10 including a circuit board mounted within said pod housing, the respective switches being mounted on said circuit board, each switch in a said pair being located on the opposite side of the board from the other switch in that pair, and said pairs of switch actuators being positioned relative to said circuit board such that each input member and associated switch-contacting portion of a said pair are operatively disposed on opposite sides of said circuit board to effect operation of the respective switches.

12. The control pod of claim 11 wherein the circuit board is affixed to said housing and said commonly-joined pairs of switch actuators cumulatively include mounting means for connected engagement with said circuit board, said pairs of switch actuators being in connected engagement with said circuit board to maintain a fixed relationship therebetween.

13. The control pod of claim 12 wherein said circuit board includes a plurality of spaced openings extending therethrough, said mounting means on said joined pairs of switch actuators comprises a plurality of mounting tabs extending from said spine and having openings therethrough in alignment with respective said openings in said circuit board, and including fastening means extending through said aligned openings for maintaining said switch actuators and circuit board in connected engagement.

14. The control pod of claim 12 wherein said control input portion of said housing including a respective opening therethrough for allowing manual actuating engagement with the respective said tactile input regions of said pairs of switch actuators, each said tactile input region of a said switch actuator including a flange portion extending therefrom beyond the perimeter of said housing opening to limit movement of said actuator outwardly of said housing, and wherein said switch actuators are configured and positioned, relative to said housing, such that said actuators are biased to a rest position with said flange portions thereof in engagement with the interior of said housing.

15. The control pod of claim 9 further including means responsive to the actuation of each switch of said pair of functionally-related pair of switches for visually indicating said actuation of a respective said switch, said indicating means being located in said pod housing in proximity with said respective pair of switch actuators and being positioned for easy visual access by an operator.

16. A switch assembly comprising:

a circuit board;

a pair of functionally-related switches, each said switch being actuated in response to a respective mechanical input stimulus, each switch of said pair being mounted on an opposite side of circuit board from the other;

a pair of integrally-formed switch actuators, said actuators comprising a respective pair of tactile input members extending in generally opposite directions from a common, transversely-extending midsection, each tactile input member including a switch-contacting portion integrally formed thereon for delivering a mechanical input stimulus to a respective one of said switches, each tactile input member being resiliently deflectable about said actuator midsection to displace said switch-contacting portion; and

means connecting said pair of switch actuators to said circuit board adjacent to an edge of said circuit board that each said tactile input member and switch-contacting portion of said pair extends to a respective side of said circuit board for actuation of the respective said switch mounted thereon.

17. The switch assembly of claim 16 wherein said means connecting said pair of switch actuators to said circuit board substantially prevents rotational displacement of said actuator midsection.
