Ratchet relay button on panel, what does it do?

[-0303-]

It's a button on the instrument panel. Wiki defines:

 

Quote

In another type, a ratchet relay has a ratchet mechanism that holds the contacts closed after the coil is momentarily energized. A second impulse, in the same or a separate coil, releases the contacts.^[17] This type may be found in certain cars, for headlamp dipping and other functions where alternating operation on each switch actuation is needed.

 

I hadn't noticed this button before and now I wonder what it controls.

Also hadn't noticed clickable left and right machine gun reload handle.

 

Err ... If mod can move this to I-16 forum that'd be great.

Hi -

 

I thought this last night, and clicked it a few times........nothing happened as far as I know.......maybe it tunes the radio 

 

In addition, there should be 4 machine gun reload levers, two right at the top of the cockpit that are quite hard to see, one either side and then two down by your left knee.
