Switching mechanism for tuning position check - has threaded piece as contact support mechanically coupled to adjustable part of automatically-tuned transmitter component

摘要

The switching device provides confirmation of correct tuning for automatically tuned transmitter components such as capacitors and coils. A contact support is mechanically coupled to a mechanically-adjustable part of the component to be tuned. Its contact touches corresponding check-back positions indicator contacts in discrete stages. A coaxial spindle (5) with a thread is fixedly installed inside a closed cylinder. A threaded piece (11) can move along the thread of the spindle by rotation. At least two follower rods (9, 10) extend eccentrically in the axial direction through the threaded piece (11) so that it can be rotated by them. The rods are fixed in a follower disc (7) at one end of the cylinder.
