bathroom vent time delay switch..

[jugglesm]

Hiall , my electrician is installing a QF100SX50P Manrose Quiet Fan X5 and an isolation switch in a new en suite. This will be wired on the bathroom lighting circuit (6242Y Grey 1mm² Twin & Earth Cable) but not affected by the bathroom light switch. I'd like him to add a time delay button, which we can press to turn the vent on for a set amount of time.

Would this work with my 2-wire system?
