[Star wats] My Jedi master says only the Jedi can activate a lightsaber is that true?

Some lightsabers.   
Some have a switch.  
Some have a dial.    
Some have a knob.  
Some have an internal switch that's telekinetically activated.     
Your Master must be pushing you towards constructing a lightsaber with an internal switch.   
     
The Jedi council's stance on Jedi Masters seeming strange or unorthodox in their methods and teachings is to just do as they say.      
Question them, but trust their words.
