What is Toggle Pins ?

On aircraft, they are basically a quick release pin especially for latching things like covers or other often opened access points. They come in many different forms and are designed for many different applications not just aviation. However in aircraft terms, flush Dzus fasteners are more widely used today although in saying that,  some do look like pins as well!!  With such a large number of designs to suit many varied applications, Google is your friend for this one. 

Here is an AI answer which explains the key elements of a toggle pin, that is a pivot point on which to 'toggle' back and forth and a spring mechanism to help secure it in the locked toggle position.  

 

A "toggle pin" is called such because it has a mechanism that allows it to "toggle" or flip back and forth on a pivot point, essentially acting like a small lever that can be easily engaged and disengaged, often with a spring mechanism to secure it in place; this design is particularly useful for quickly connecting or disconnecting parts in various applications like rigging, marine hardware, or industrial machinery. 

Key points about toggle pins:

"Toggle" action:

The key feature is the ability to flip or "toggle" the pin to securely fasten or release it. 

Spring mechanism:

Many toggle pins incorporate a spring to maintain tension and ensure a secure connection. 

Applications:

Used in situations where quick and reliable fastening is needed, like connecting sections of containment boom during an oil spill or attaching rigging lines on a boat.
