The MAGNASPHERE is also a superior replacement for Hall Effect switches as it doesn’t require a third wire as a power source, drain battery supply during stand-by, require an RFI/EMI protective filter, or require a shielded wire harness. Compared to the Hall Effect switches, the Magnasphere operates on similar magnetic field strengths, senses more than one magnetic polarity, uses similar amount of PCB area, and is robust to shock forces and impact.
