There's s hotel resident asking the receptionist that the AC doesn't work . so the worker told him "スイッチをぎじゅつしゃ押してください" I don't know what's the meaning of "ぎじゅつしゃ" here ?
ぎじゅつしゃ is in kanji 技術者, which means 'engineers' in general.
In this case most sufficient translation would be technical service or electricians.
And the original sentence would be
Call the electricians for the switch, please.
Then, the sentence makes a little sense. Anyway get back and check with the source.
