ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. As a safety precaution, the magnetic switches are packaged in TO-236-3, SC-59, SOT-23-3 packages. Good performance is achieved by powering the magnetic switches with 10μA as the maximum current. Magnetic switches should have a maximum current of 1mA to operate.
