Description
Experience Level: Expert
My project ( almost finished ) needs small improvements.
2 improvements, to be precise
1) A mechanism that locks the "whistle" in the open position (specifically, at the 180-degree mark).
Upon opening, once it reaches that position, the whistle is immobilized.
Afterward, pressing a button releases it, allowing it to be retracted.
2. The whistle is retracted. Pressing the small button causes it to pop up by approximately 5 mm.( something similar to pen mechanism ? )
Once finished, the whistle is pushed back down.

Would you prefer one button to control both functions releasing the whistle from the 180° locked position and triggering the 5 mm pop up or should these remain two independent mechanisms?
