New Switch, Round (Revised)

For people who want to operate ICT devices using a switch

This is an updated design that solves the problem of the circuit board moving up and down when using this switch. A part inserted from the side of the switch box holds the board in place, and a small separately printed part attached to the metal portion of the microswitch lets the switch respond to presses from various angles. Along with these improvements, we made the top pressing surface in a flat shape and also created a dome-shaped version. Please choose whichever is easier for the user to press.

How

This shape is designed specifically for the earphone-jack circuit board sold by the ICT Rehabilitation Research Lab (NPO). It can be used easily without soldering. The data includes two types of 3D-printed "springs." These are installed inside the main body. You can use three levels of pressing force: "Spring 1.2mm," "Spring 0.8mm," and "No spring." Please print with Layer height = 0.12mm.
