In order to prevent damage, the magnetic switch is packaged in the Tape & Box (TB). It is necessary to put the magnetic switches into 3-SIP, Formed Leads packages in order to ensure their safety. The maximum current that can be output by these switches is 25mA. There is a maximum current limit of 6mA that can be supplied by these switches. Switches have 3 pins for operation. 3 terminations are contained in it. There should be 25mA current output from the switches in general.
