The present invention is directed to the improved mounting and disposition of a series of magnetic switching members utilized to convert the characters printed on a keyboard into coded electrical signals, generally wherein each switch is opened or closed in response to movement of each of a selected group of interposers which control printing of each character on the keyboard. Each of the magnetic switch elements is mounted on the back of a circuit board, and a magnetic switch-actuating member for each switch is releasably inserted in the slotted end of a holder which in turn is attached in close-fitting relation to an interposer so that the actuating member is securely but adjustably disposed for movement in response to movement of its interposer in closely spaced parallel relation to a switch.
