Are There Any Points To Look Out For wWhen Changing Over From 61F-APN Alternate Operation Relays To 61F-APN2?

61F-APN and 61F-APN2 differ in outer dimensions, so the compatible Sockets and the mounting method will be different. This means that the Sockets must also be replaced, and the terminal arrangement will be reversed, so the wiring will have to be changed as well.
