Mains relay for fan boost

[John D v2.0]

Hi all, just wonder does anyone have any suggestion.
I have an existing light switch with cable plastered in. I want to switch the fan to boost when the light is on (and ideally for a period afterwards). The old fan was simply powered on with the light.
Boost on the fan controller is simply shorting out two elv 10v pins on the controller.
Does anyone have a suggestion of a simple relay with mains input suitable for switching 10v? Ideally with an enclosure and terminals rather than just a bare relay.
Cheers, John

how old do you think the fan is?

A suitable relay is the Finder Part Number 40.31.7.230.0000 which plugs into socket Part Number 95.83..3 which has screw terminals.

This combination fits nicely into a two module enclosure such as

NOTE when selecting relay and socket be aware that some relays have pins on a 5mm pitch (40.51) and some have pins on 3.5mm pitch (40.31)

About 5 years from manufacture date, it's a duplex vent dv72.
