Abstract

Methods, systems, apparatuses, and computer program products are provided for a user input device, such as a game controller, that includes a finger-pressable (“tactile”) switch. The switch is adjustable to change the amount of force used to actuate the switch. In an example implementation, a tactile switch comprises a housing, a button interposer, a dome switch, and an adjustment mechanism. A user or other entity may press the button interposer. The dome switch is contained in the housing, and is actuated by the button interposer being pressed. The adjustment mechanism is contained at least partially in the housing, and is configured to enable an amount of force used to press the button interposer to actuate the dome switch to be adjusted.

First claim

What is claimed is:

1. A tactile switch, comprising:
a housing;
a button interposer;
a dome switch contained in the housing that is configured to be actuated by pressing the button interposer; and
an adjustment mechanism contained at least partially in the housing, the adjustment mechanism including a lever arm and a fulcrum that is slideable to adjust an amount of force involved to actuate the dome switch by changing a pivot point on the lever arm where the lever arm rotates about the fulcrum.

2. The tactile switch of claim 1 , wherein the lever arm has opposing first and second end portions and opposing first and second surfaces, such that the first surface of the lever arm receives a surface of the button interposer, the second surface of the lever arm at the first end portion contacts the fulcrum, and the second surface of the lever arm at the second end portion is coupled to the dome switch.

3. The tactile switch of claim 2 , wherein the fulcrum has a handle that extends through an opening in a surface of the housing, and is configured to be moveable to slide the fulcrum relative to the second surface of the lever arm to adjust the amount of the force.

4. The tactile switch of claim 3 , wherein the handle slid to position the fulcrum closer to the first end portion of the lever arm reduces the amount of force used to press the button interposer to actuate the dome switch, and the handle slid to position the fulcrum closer to the second end portion of the lever arm increases the amount of force used to press the button interposer to actuate the dome switch.

5. The tactile switch of claim 1 , wherein the lever arm is T-shaped.

6. The tactile switch of claim 1 , wherein the button interposer is hat shaped.

7. The tactile switch of claim 1 , wherein the button interposer includes flanges movable to interface the button interposer and the housing.

8. A user input device, comprising:
a device housing; and
a tactile switch mounted to the device housing, the tactile switch comprising:
a switch housing;
a button interposer;
a dome switch contained in the switch housing that is configured to be actuated by pressing the button interposer; and
an adjustment mechanism contained at least partially in the switch housing, the adjustment mechanism including a lever arm and a fulcrum that is slideable to adjust an amount of force involved to actuate the dome switch by changing a pivot point on the lever arm where the lever arm rotates about the fulcrum.

9. The user input device of claim 8 , wherein the lever arm has opposing first and second end portions and opposing first and second surfaces, such that the first surface of the lever arm receives a surface of the button interposer, the second surface of the lever arm at the first end portion contacts the fulcrum, and the second surface of the lever arm at the second end portion is coupled to the dome switch.

10. The user input device of claim 9 , wherein the fulcrum has a handle that extends through an opening in a surface of the housing, and is configured to be moveable to slide the fulcrum relative to the second surface of the lever arm to adjust the amount of the force.

11. The user input device of claim 10 , wherein the handle slid to position the fulcrum closer to the first end portion of the lever arm reduces the amount of force used to press the button interposer to actuate the dome switch, and the handle slid to position the fulcrum closer to the second end portion of the lever arm increases the amount of force used to press the button interposer to actuate the dome switch.

12. The user input device of claim 8 , wherein the lever arm is T-shaped.

13. The user input device of claim 8 , wherein the button interposer is hat shaped.

14. The user input device of claim 8 , wherein the button interposer includes flanges movable to interface the button interposer and the device housing.

15. A method for a tactile switch, comprising:
configuring a button interposer of the tactile switch to be pressable to actuate a dome switch in a housing of the tactile switch; and
configuring a lever arm and a fulcrum of an adjustment mechanism of the tactile switch to enable an amount of force used to press the button interposer to actuate the dome switch to be adjustable by sliding the fulcrum to change a pivot point on the lever arm where the lever arm rotates about the fulcrum.

16. The method of claim 15 , wherein said configuring the lever arm and fulcrum comprises:
configuring the lever arm to have opposing first and second end portions and opposing first and second surfaces, such that the first surface of the lever arm is configured to receive a surface of the button interposer, the second surface of the lever arm at the first end portion is configured to contact the fulcrum, and the second surface of the lever arm at the second end portion is configured to be coupled to the dome switch.

17. The method of claim 16 , wherein said configuring the lever arm and fulcrum further comprises:
configuring the fulcrum to have a handle that extends through an opening in a surface of the housing, the handle configured to be moveable to slide the fulcrum relative to the second surface of the lever arm to adjust the amount of the force.

18. The method of claim 17 , wherein the lever arm is T-shaped.

19. The method of claim 15 , wherein the button interposer is hat shaped.

20. The method of claim 15 , wherein the button interposer includes flanges movable to interface the button interposer and the housing.
