Abstract (en)
[origin: EP0290010A2] The invention relates to a switching device for a door or gate, with an electrical door or gate actuation device (14, 14'), with a key switch (11, 11') which can be brought selectively into an "on" or "off" position and which is for switching on the door or gate actuation device (14, 14'), and with a coding keypad (17) which acts on a relay (12) having a second switch (13) and which energises this for a predetermined time only after a predetermined key combination has been keyed in. The coding keypad (17) is independent of the key switch (11), and the second switch (13) is in series with the key switch (11, 11') in the power-supply line (30, 34') for the door or gate actuation device (14'), so that this can be put into operation only when both the key switch (11, 11') and the second switch (13) are closed. <IMAGE>
