I don't have an RT-AC68U, otherwise I'd figure it out.Does anyone know switch symbol fin asus rt-ac68u?
From the photos, it looks like a common, easy-to-find tactile switch or pushbutton switch. So all you have to do is measure the dimensions in mm:
a) x and y dimensions of the body
b) x and y distances between the pins (looks like six pins total in two rows of three)
c) z dimension of body (not including actuator)
d) z dimension of actuator, sticking above the body, without any removable button cap on the actuator
e) shape of actuator cross-section (round or square, usually), and x and y dimensions of the actuator
Then, the only other necessary measurement is how the switch behaves electrically and whether the actuator is latching or momentary.
With all that info, it should be easy to look up the correct part number.
The switch probably costs no more than $0.50 each.
These switches look similar. Check out the datasheet and note the dimensions that you will have to measure:
I am not saying that the switch is one of these switches. They just look a lot like the photos.
