MAGNASPHERE SWITCHES are also a superior replacement for Hall effect switches. • Does not require a third wire as a power source. • Does not drain battery supply during stand-by. • Operates on similar magnetic field strengths. • Does not require RFI/EMI protective filter. • Does not sense only one magnetic polarity. • Uses similar PCB “real estate” area. • Does not require shielded wire harness. • Robust to shock forces and impact.
