This is a medium sized micro switch, commonly used as limit switches, door-open switches and things like that. I have different styles available, you choose which one you want…
Note that there are some minor batch-to-batch variarions, some are “Inner” hinged and some are “Outer” hinged, and may be subtle variation in the width of the arm. Which of those minor variations you get is random (doesn’t affect the switch usage or electrical specifications) but if you really deeply care about the exact arm measurement then just ask a question and I can check which I have in stock for you.
Dimensions of the body excluding arm are approx 20mm long, 6.6mm wide, and 14.3mm high, holes in the side for screw mounting are 2.5mm diameter with 9.6mm pitch,
3 legs, the one nearest the switch nub end is common, the one in the middle is normally open, and the last one is normally closed.
