I was expecting it to be smaller, the size was listed in the description, but I don't know metric so my bad. I was making a crystal radio and needed a period look. I was able to cannibalize two switches, shorten the blade, attach a porcelain knob, replace the plastic thumb connections with brass ones and mount them on a ceramic base and It turned out great. ### ⭐⭐⭐⭐⭐ Better than others I have used *by on Reviewed in the United States February 3, 2023* Purchased for use in displays where I have to cut the power to a small 12 volt system.works good and engages where it will not come lose very easy. ## Frequently Bought Together - tatoko 5PCS Educational Single Pole Knife Switch Physics Laboratory Equipment Single Pole Single Throw (SPST) Switch - 30 Pieces E10 Screw Mini Bulbs Warm White Bulb Light and E10 Mini Screw Type Socket Black Plastic Lamp Holder for Student Experiment Lighting DIY Accessories (1.5V, 0.3A) - WGGE WG-026 10 Pieces and 5 Colors Test Lead Set & Alligator Clips,20.5 inches / 22 AWG Copper Wire.
