Integral functional unit containing reed switch, has provision for tracks and mounting of all associated electrical components, especially series and parallel resistors

摘要

The support (2) carries conductive tracks with connections to the reed switch (3). Regions (B) are included for electrical and non-electrical components. Further components are included in prepared locations. These include a protective cap for the reed switch (3) and a protective cap for at least part of the support (2). Electrical components are included, especially resistors (5, 6) connected in parallel and/or series with the reed switch. The equipment connector (7) includes contacts (9) connected to the tracks. An attachment (11) is also included. Surface mounting devices are used.
