Locking Thumb Shifter?
 
Anyone know who made these? or what the purpose of a locking shifter is?

maybe similar to the portacatena lockout available on campy downtube shifters for a hot minute?

For a dropper seatpost perhaps?

Parking brake?

Perhaps this is not intended for bicycles since handle bars for many things are close to the same size. But even with broadening the thinking, I'm still at a loss.

Perhaps to set the throttle on a small boat or machine?
