idiomatic expression for please ring the doorbell

[Dogberry]

I spend most of my time while at home upstairs and usually with music on. When the mail person or whomever else hails the house I rarely hear them. I have a door bell but it looks more like a light switch than anything. I'd like to label the bell with the correct idiomatic expression (Plunk Your Magic Twanger Froggy!?) to draw attention to it. Thanks in advance!

Don't speak Thai but this seems to work at my house

กดออด press the buzzer
