E-Stop Switch Question

Hello, we're looking at using this switch: for our emergency stop. We would place a red marking around it to signify that it is the E-stop, however it is a rotary type switch. It is not depressed, but instead a knob is rotated to turn the E-stop on and off. Thoughts?

We had a similar kill switch

We had a similar kill switch design last year that required the diver to rotate the switch. We received some comments from divers that they would rather a switch which they can pull not twist.

While in practice that switch is fine, if something were to go wrong with your sub, a push to kill switch would be much easier for the diver than one that has to rotate. A rotating switch would take two hands to use (one to grab the sub, the other to rotate the switch).
