you can buy a 12v lever switch if you're so inclined, I used to use them for hood and trunk switches in my vehicles. but essentially that's just metal touching metal. traveling 1-2 meters irrelevant at the amps you're dealing with and would dictate wire size nothing else. first come up with a mechanism you like and can print (print in place spring would be my choice) and then it's just putting two bits of metal that contact on depression, or in your pics case a 3rd that contacts both.
