Abstract

The switch matrix has a number of two-position switches whose contacts are sealed in an envelope. Each switch is controlled by electrically first and second independent coils. The first coil has two halves wound in opposite sense to magnetic respective contacts of the switch. The first coils are in columns each including a selection relay coil. The second coils are connected in lines with each column controlled by a selection relay. Energising one column of the first coils opens the column switches and closes the selection relay. Energising one line cancels half of the first coil and closes switch.
