Abstract (en)
[origin: US6959568B2] An apparatus indicates the closure state of a key-operated lock, having a housing that is fitted to the key and has a rotation detection sensor which is held therein and comprises a hollow body that is filled with a first electrically conductive liquid and has electrically conductive contacts for production of electrical contact sequences which are dependent on the closing direction, and having an electronic evaluation unit which uses the contact sequences to determine the closure state of the lock. The hollow body is substantially completely filled with the first electrically conductive liquid and with a second electrically non-conductive fluid that repels the first liquid.
