Narrative:
During taxi into the gate at ZZZ while setting up for single engine taxi; I inadvertently selected the number 1 engine gen switch off while intending to turn off the APU gen switch to prevent a potential power cycle for a pending APU start. Because the number 2 engine gen had already been turned off in preparation for single engine taxi (and awaiting the required 3 minutes for engine shutdown) switch misidentification resulted in a momentary loss of electrical power also effecting the nose wheel steering and brakes. The error was immediately noticed and power was reapplied retuning power; steering and braking immediately without incident.
