Bistable Compliant Switch

cults3d

This bistable switch exemplifies a compliant mechanism that leverages a four-bar mechanism pseudo-rigid-body model. A contact force is generated when the contacts connect prior to reaching the second stable equilibrium position. Living hinges are utilized at other joints. This mechanism has potential applications as a fully compliant electrical switch or in various other capacities, such as cabinet door hinges. This bistable switch can be created through 3D printing or milling. For optimal performance, milling or cutting with polypropylene yields superior results. When opting for 3D printing, the choice of filament material and its fatigue/flex properties will determine the number of cycles it can withstand. Consult print settings accordingly.
