Vertical MB-1 with lockable button switch
One feature lacking on my standard vertical MB-1 modifications is a release lock mechanism. Hence false triggers can occur when the switch is accidentally pressed. So I added a MF-1 button switch to this MB-1. It has a locking mechanism so that false triggers are prevented when the switch is not in use.
