有線遙控器

Snapped it on to replace the old one, and the tactile click on each button is much more satisfying. The coiled cable gives just enough reach without tangling, which is a nice improvement.

The twelve buttons are laid out clearly enough that I didn’t have to look down much during alignment work, and the cable length gives me plenty of room to move around the setup. It’s a solid spare part that does exactly what it’s supposed to do, no fuss.

Plugging this in was surprisingly easy, and the buttons have a satisfying, solid click that gives good tactile feedback. It’s a straightforward upgrade for anyone needing precise remote control over their interferometer setup.
