Hi, I was a bit frustrated with the ergonomics of the standard switch behind the gripper of the Wise 2086 tension head. Was just hard to find the little red button. I have made a 3D printed assembly of two parts which can fit over the standard switch and make hitting the button very easy and ergonomic. It is basically a bracket which fits over the switch and a small lever which has a contact srface to the switch and a lever which site just behind the gripper plates. If anyone is interested send me PM.
