Keyboard change-over switch

If you have a non-qwerty keyboard and would like to use this with your computer without having to reIearn where the deviating keys are, this simple circuit will help. lt receives two keyboards on K2 and K3 respectiveIy and connects these via switch S1 and connector K1 to the computer. Check the keyboard connections at your cornputer, because some PC compatibles have a slightly different pin layout. The connection between the circuit and the computer is via a standard 5-way DIN cable; you can, of course, make your own cable as shown at the bottom of the diagram (K4 and K5).
