Doorbell
thingiverse
This replacement doorbell comes with a detachable plinth that can be printed to match your home's unique style. The button itself can be customized in clear and illuminated designs if you prefer a sleeker look. Two tactile switches, similar to these (http://media.rs-online.com/t_large/F7581938-01.jpg), are soldered onto a small strip of circuit board attached to the backplate. These switches work in tandem, so closing either one triggers the doorbell's sound. I've also added a small spring between the stripboard and button for extra stability, as well as a 3mm LED light on my model.
