It was to take the place of the view-selector keys in the computer flight simulations. As you turn your head right, your gaze is to the left so the left view is on the monitor. The wires are soldered in parallel to the keyboard keyswitches. We got a second keyboard to use for the cockpit. But all game vendors use different keys for views.
Some vendors even use different keys for different flight sims.
And some punish you by making you use multiple keystrokes. So either select your best game, use a rotary switcher with a position for each vendor, or use programmable keys. It can be replaced by the head-switcher. Five resistors are on the five-position hat switch, which uses two of the eleven wires. The other wires go to buttons or the trigger.
