All of our big commercial CNC routers have a single tool release button. Our Anderson (Omnitech), Komo, and Northwood, all have a single momentary switch that only opens the drawbar while you hold the button down. Our SCM Routech, is a little different and the momentary switch is used as an input to the PLC, and behaves like a toggle, one press releases, second press grabs the tool. And all of them have multiple interlocks through their PLCs to prevent using the manual tool releases under normal circumstances, involving multiple button presses/mode changes, and even m-code inputs to enable the manual tool release. It would be difficult or even impossible to manually change a tool during normal execution of a program on most of these machines.
The location of the tool release button is varied. Some machines have the button on the spindle. Some have it on the tool carousel. Some are on the pendant. I think there might be a procedure for doing a manual change during program execution on our Komos but have never used it. The manual procedure would be intended for using large aggregate tooling that might be too large to ride in the tool changer carousel. The others I am not sure have any way. Our SCM has an M-code to enable a "special" tool change, but I think that may just disable some of the tool pockets. Todd Zuercher P.

I believe (but could be wrong) that Haas machines use a single momentary switch on the head to release the drawbar.
