The individually specified maximum electrical values of the reed switch must 
never be exceeded, even for a moment. Higher switching values may reduce the 
service life or even destroy the contact.  
For capacitive and inductive loads (e.g. via long lines), we recommend the 
following protective circuits: 

Lamp load with series or parallel 

Protection with a RC suppressor  

resistance to the reed switch. 

For  a.c. current and inductive load.

Protection with a diode  

Protection with an inductance or  

for d.c. current and inductive load. 

Resistance for capacitive load.
