If you mean main power switch (master switch) - it's your choice, the board reliably works without it, but you can use it for more safety. To vape you have to use normally opened button: tact button
I use this schematic of the button. Depending on the LED and input voltage you can lower R2 to, say, 1 Kohm. R1 - any 5-10-50 Kohm resistor.
