How to tell when a UISwitch inside of a UITableViewCell has been tapped?

My UISwitch is set up inside of the cell (generic cell) like this:

UISwitch *mySwitch = [[[UISwitch alloc] initWithFrame:CGRectZero] autorelease];
[cell addSubview:mySwitch];
cell.accessoryView = mySwitch;

And I am trying to detect a tap like this (but its not working):

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {

    NSUserDefaults *prefs;


    if(indexPath.section == 1){

        switch(indexPath.row)
        {
            case 0:

                NSLog(@"Tapped Login Switch");              

                break;
            default:
                break;
        }

    }


}
