Abstract

A toggle button assembly for a human-machine interface (HMI). The toggle button assembly includes a circuit board. A first switch and a second switch are mounted to the circuit board. A toggle body is rotatable about a toggle body rotation axis. A first switch actuator is between the toggle body and the first switch, and a second switch actuator is between the toggle body and the second switch. Upon actuation of the toggle body from a center position to a first position, the toggle body rotates about the toggle body rotation axis and presses the first switch actuator against the first switch to actuate the first switch. Upon actuation of the toggle body from the center position to a second position, the toggle body rotates about the toggle body rotation axis and presses the second switch actuator against the second switch to actuate the second switch.

First claim

What is claimed is:

1. A toggle button assembly for a human-machine interface (HMI), the toggle button assembly comprising:
a circuit board;
a first switch mounted to the circuit board;
a second switch mounted to the circuit board;
a toggle body rotatable about a toggle body rotation axis;
a first switch actuator between the toggle body and the first switch, the first switch actuator including a first switch actuator mount and a first switch actuator arm;
a first switch actuator rotation shaft extends from the first switch actuator mount, the first switch actuator rotation shaft rotates about a first switch actuator rotation axis;
a second switch actuator between the toggle body and the second switch, the second switch actuator including a second switch actuator mount and a second switch actuator arm; and
a second switch actuator rotation shaft extends from the second switch actuator mount, the second switch actuator rotation shaft rotates about a second switch actuator rotation axis;
wherein upon actuation of the toggle body from a center position to a first position, the toggle body rotates about the toggle body rotation axis and presses the first switch actuator against the first switch to actuate the first switch;
wherein actuation of the toggle body from the center position to the first position presses a first tab extending from the toggle body against the first switch actuator arm, which presses against the first switch to actuate the first switch;
wherein upon actuation of the toggle body from the center position to a second position, the toggle body rotates about the toggle body rotation axis and presses the second switch actuator against the second switch to actuate the second switch;
wherein actuation of the toggle body from the center position to the second position presses a second tab extending from the toggle body against the second switch actuator arm, which presses against the second switch to actuate the second switch; and
wherein the toggle body rotation axis, the first switch actuator rotation axis, and the second switch actuator rotation axis all extend in parallel to one another.

2. The toggle button assembly of claim 1 , wherein the first switch and the second switch are mounted to the circuit board vertically offset from one another.

3. The toggle button assembly of claim 1 , wherein the first switch and the second switch are both tact switches, or both include rubber elastomer domes with carbon pills.

4. The toggle button assembly of claim 1 , wherein the first switch and the second switch are preloaded in an outward position to bias the toggle body in the center position, return the toggle body from the first position to the center position, and return the toggle body from the second position to the center position.

5. The toggle button assembly of claim 1 , wherein the toggle button assembly includes only a single circuit board.

6. The toggle button assembly of claim 1 , wherein the toggle body is connected to a first toggle body rotation shaft and a second toggle body rotation shaft, each one of the first and second toggle body rotation shafts extends along the toggle body rotation axis.

7. The toggle button assembly of claim 6 , further comprising a base to which the circuit board is mounted, each one of the first toggle body rotation shaft, the second toggle body rotation shaft, the first switch actuator shaft, and the second switch actuator shaft is mounted to the base.

8. A toggle button assembly for a human-machine interface (HMI), the toggle button assembly comprising:
a first switch depressible from an outward position to an inward position, the first switch biased in the outward position;
a second switch depressible from an outward position to an inward position, the second switch biased in the outward position;
a circuit board to which the first switch and the second switch are mounted;
a toggle body rotatable about a toggle body rotation axis;
a first switch actuator between the toggle body and the first switch, the first switch actuator including a first switch actuator mount and a first switch actuator arm;
a first switch actuator rotation shaft extends from the first switch actuator mount, the first switch actuator rotation shaft rotates about a first switch actuator rotation axis
a second switch actuator between the toggle body and the second switch, the second switch actuator including a second switch actuator mount and a second switch actuator arm;
a second switch actuator rotation shaft extends from the second switch actuator mount, the second switch actuator rotation shaft rotates about a second switch actuator rotation axis;
wherein actuation of the toggle body from a neutral position to a first position presses the first switch actuator against the first switch to move the first switch from the outward position to the inward position;
wherein actuation of the toggle body from the neutral position to the first position presses a first tab extending from the toggle body against the first actuator arm, which presses against the first switch to actuate the first switch;
wherein actuation of the toggle body from the neutral position to a second position presses the second switch actuator against the second switch to move the second switch from the outward position to the inward position;
wherein actuation of the toggle body from the neutral position to the second position presses a second tab extending from the toggle body against the second actuator arm, which presses against the second switch to actuate the second switch; and
wherein the toggle body rotation axis, the first switch actuator rotation axis, and the second switch actuator rotation axis all extend in parallel to one another.

9. The toggle button assembly of claim 8 , wherein the toggle body is biased to return to the neutral position from the first position and from the second position.

10. The toggle button assembly of claim 8 , wherein a longitudinal axis of the toggle body extends perpendicular to the toggle body rotation axis.

11. The toggle button assembly of claim 8 , wherein the first switch actuator rotation axis and the second switch actuator rotation axis are vertically offset from one another.

12. The toggle button assembly of claim 8 , wherein the first switch and the second switch are mounted to the circuit board vertically offset from one another.

13. The toggle button assembly of 8 , wherein the first switch and the second switch are both tact switches, or both include rubber elastomer domes with carbon pills.

14. The toggle button assembly of claim 8 , wherein the toggle button assembly includes only a single circuit board.

15. The toggle button assembly of claim 8 , wherein:
upon release of the toggle body after the toggle body has been actuated to the first position, the first switch moves to the outward position, which presses the first switch actuator against the toggle body to move the toggle body back to the neutral position; and
upon release of the toggle body after the toggle body has been actuated to the second position, the second switch moves to the outward position, which presses the second switch actuator against the toggle body to move the toggle body back to the neutral position.

16. The toggle button assembly of claim 8 , further comprising a base;
wherein the circuit board, the toggle body, the first switch actuator, and the second switch actuator are each mounted to the base.
