Abstract

The loack actuated with push button has variable code. The lock is released when the push buttons are operated in a certain sequence, otherwise an alarm will be triggered. A keyboard has a rotating button switch arrangement and programme control circuit. The connection to the working contact of the rotating switches and the connection to the different push buttons of the keyboard can be established while the centre tapping or the contact of the rotating switches at rest are connected with the input connections of the programme control circuit or with the sequential circuit. Hence the programme or the control sequence of the programme control circuit or the sequential circuit can be varied by the rotation of rotating buttons.
