Towards a cost-rffective simplified mechanical fuse: A feasibility study

Conventional fuses rely on electrical and thermal overload to function, however, there is a gap in the market for a single-use mechanical fuse [1, 2] that fails under controlled shear force and is easy to actuate. This type of fuse can be used in switching circuits for braking systems. In this abstract, the mechanical formation of the fuse is explored along with a comparative analysis of structural material supported by finite element analysis (FEA). Physical testing of the fuse is evaluated using a custom rig breakage force, notch design, and actuator geometry. Results confirm the fuse's viability for applications requiring electrical safety and anti-tampering.
