These cool switchplates are by Green Tree Jewelry. The whimsical designs are made of wooden pieces laser cut to resemble gears and other machine parts. The maker is based in San Diego. I own a pair of their earrings, so I can attest to the wood being cut precisely and finished smoothly.
Peruse the company's wares at their website and Etsy site, and follow them on social media at Facebook, Twitter and Instagram.
Why are US switches so ugly? And impractical - hard to use for kids, old people, people with their hands full - just generally weird to stick with such an old fashioned design.
