Switch to change direction

[garage nut]

Perhaps my question got a bit lost in the "Power Hacksaw" Tread.
So here I go.

I have a 220V AC induction motor that allows me to change the direction by switching the a "BRIDGE" and the Capacitor internally. There is a sketch in the other tread.

I need some ideas as how to do this with a switch. What type of switch must I ask for and do I need to fit a second capacitor?or has somebody got a cheap DIY method.

I did go through the Electrical/Switches section.
