Need help to find a device

hi guys, i hope someone can help me. i’m looking for a coin operated power device (taiwan made), the kind of device one might use with a washing machine or regulate internet usage. a small box with a coin slot and a controlable power timer, when time is up power to the attached machine cuts out. ive seen ones made in the US and the UK, but so far ive had no luck here. I’d really apperciate any advice or leads.
thanks all,
chris bryant
