- If the air plane was eventually hit and going down, the operator would push the spring with the roller towards the key handle - with the key down - Then the key will then be locked in transmission mode. This was used to let friendly forces track the air plane by radio direction finding systems and to guide them to the crash site, which was mostly in water.
This way they could possibly have the approximate location to rescue surviving crew.
This is the only key type that I know of that has this feature.

- Including a rubber diaphragm under the knob,the key's design ensured sparks from its contacts were isolated, thereby avoiding explosions caused by igniting petrol vapour.
