Where is the Main POWER leg of the nRF52832, If I want to add an ON/OFF Switch - for cutting the POWER to the all Bluetooth chip?

If I look in the schematic of the nRF52832 I see 3 VDD Legs (leg 13, leg 36, and leg 48), What is the leg number for the main power to the chip, that if I cut his power supply then the all chip is turning off?

And if I add an ON/OFF switch to it then it cut all the power to the all nRF52832 chip.

Main power is shared between those 3 pins, so you need to cut them all from your power supply. There is no single pin to cut power.

Then I need to add 3 switches of ON/OFF to the circuit ?

[Stefan Wyss]

No, you could route the tracks from all 3 pins together on 1 ON/OFF switch.
