WPF suspending key presses for a slower movement

In my game, my character is moving, but my problem is, that if I keep pressing the buttons he reaches supersonic speed and runs very fast. Which is not good.

What do you suggest how to put a "wait" in the code to simulate a more realistic moving?

I tried System.Threading.Thread.Sleep but it was a dead end. It suspended the whole program. And the enemies stopped.

I'm using a DispatcherTImer in the program for the enemy moving maybe it is the solution but i wasn't able to figure out.

I have this keydown event:

private void Window_KeyDown_1(object sender, KeyEventArgs e)
{
    if (e.Key == Key.H)
    {
        //Jatek.Player.Hack();
    }
    else if (e.Key == Key.Up)
    {
        jatek.PlayerMovement(MozgasIrany.Up,Field);

    }
    else if (e.Key == Key.Down)
    {
        jatek.PlayerMovement(MozgasIrany.Down,Field);
    }
    else if (e.Key == Key.Left)
    {
        jatek.PlayerMovement(MozgasIrany.Left,Field);
    }
    else if (e.Key == Key.Right)
    {
        jatek.PlayerMovement(MozgasIrany.Right,Field);
    }
}

This is how I move the characters:

public void PlayerMovement(MozgasIrany irany, Canvas Aktual)
{
    switch (irany)
    {
        case MozgasIrany.Up:
            player.Move(0, -10, MozgasIrany.Up);
            break;
        case MozgasIrany.Down:
            player.Move(0, 10, MozgasIrany.Down);
            break;
        case MozgasIrany.Left:
            player.Move(-10, 0, MozgasIrany.Left);
            break;
        case MozgasIrany.Right:
            player.Move(10, 0, MozgasIrany.Right);
            break;
        default:
            break;
    }
}

public void Move(int x, int y, MozgasIrany irany)
{
    switch (irany)
    {
        case MozgasIrany.Up:
            if (alakzatTerulet.Y > 0)
            {

                alakzatTerulet.Y += y;
            }
            else
            {
                alakzatTerulet.Y = 0;
            }
            break;
        case MozgasIrany.Down:
            if (alakzatTerulet.Y < 420)
            {

                alakzatTerulet.Y += y;
            }
            else
            {
                alakzatTerulet.Y = 420;
            }
            break;
        case MozgasIrany.Left:
            if (alakzatTerulet.X > 0)
            {
                alakzatTerulet.X += x;
            }
            else
            {
                alakzatTerulet.X = 0;
            }
            break;
        case MozgasIrany.Right:
            if (alakzatTerulet.X < 610)
            {
                alakzatTerulet.X += x;
            }
            else
            {
                alakzatTerulet.X  = 610;
            }
            break;

    }
}

Rx is the way to go

I am using Sample as a way to tame the keypresses, this will take the last event every 100 milliseconds but you can use other examples see here
