Embodiment Construction

[0032] The invention relates to a key switch within the scope of this patent application, as described at the outset, for use in escalators or moving walkways. Key switch means a system or a unit which enables a certain group of persons, such as firefighters, police, tenants or the like, to put a mobile device into a desired mode, such as emergency mode, or to trigger a special operation, such as . A mechanical key is used for this, which is referred to here as a key. The invention can also be used in a smart key provided that the key has a key bit with an identifiable feature that distinguishes it from other keys.

[0033] exist figure 2 Such a key 13 is shown simplified in FIG. According to the invention, the key is a mechanical key 13 or a smart key (for example with an embedded chip), which has a key bit which is designed such that once the tooth 13.1 of the key 13 is inserted into the key receptacle of the key cylinder 16.3 16.2, the tooth mechanically interacts with...

Abstract

The invention relates to key switches (15) for drive devices having key recognition means (30) for recognizing a key (13) having key bit (13.1) and having a key receptacle for inserting the key bit (13.1). The key recognition means (30) operate without contact and have corresponding scanning means (32) for scanning at least part of the key bit (13.1). The scanning means (32) deliver actual values of a key (13) inserted in a key accommodating means (62.2). Storage means (31) are provided in order to store comparison values of a key (13) in an initialization phase. An electronic comparator (33) is provided, which compares actual values to comparison values and causes a release if the actual values and comparison values agree.

Description

technical field [0001] The invention relates to a key switch according to the preamble of claim 1 , which is designed, for example, for installation in an elevator car of an elevator installation, and also to a key switch according to the preamble of claim 14 . By means of a method of initializing a mobile device by means of such a key switch. Background technique [0002] Mobile installations such as elevator installations, moving walkways and escalators are often designed with key switches. [0003] In some countries it is stipulated that the elevator car must be operable by firefighters with the aid of a special key in the event of an emergency, such as a fire. With this key, the elevator control can be switched, for example, into a special mode (emergency mode). [0004] Other mobile devices also have a key switch operated by service personnel to be able to switch from normal operation to service mode. [0005] Mobile devices controlled by means of key switches are al...
