I have a 2024 Spyder RT Sea-to-Sky and measured the switch and took a couple of pictures, one of which is really bad.
Switch Dimensions:
height (top to bottom): 12.43 mm
width (right to left): 15.82 mm
depth (front to back, highest point): 10.83 mm
gap (between the back of the switch and the handlebar "cluster"): 2.65 mm
