A protective Tape & Reel (TR) package surrounds the magnetic switch to protect it from damage. In order to ensure safety, magnetic switches are packaged in SOT-553 packages. In order to function well, magnetic switches should be able to supply a maximum current of 8μA. When these switches are working, 3.5mA is the maximum current they can output. This switch is capable of supplying a maximum current of 8μA. Switches require 5 pins to function. In general, the current output by the switches should be 3.5mA.
