Nope! The Rxer is still using power when it is switched off. It is just not supplying power downstream of the Rxer. However, the amount of power used when the Rxer is switched off is very low. Consequently, the Rxer's switch is good for a "day switch." But if you are putting the plane away for several days or more,... now you need to either have a battery switch(s) or disconnect the battery.
