Switches are used in control circuits to limit the linear movement of mechanisms: KU-701 - with small values of run-out, KU-704, KU-706 – with any value of run-out, KU-703-limits the movement of lifting mechanisms. Switches HB-701, HB-702, VU-701, VU-702 are used in circuits of various mechanisms.

3. Installation dimensions of limit switches.
3.1. The body of influence on the drive switches are:
in KU-701, KU-706 – restrictive range of movement; in CU-704 – pin; in CU-703 – shelf, mounted on traverse crane hook, which raises or lowers the load of the operating lever of the switch.
3.2. The design provides for any order of contact closure, which can be obtained by reassembling the Cam drum at the site of operation.
3.3. Working position of switches in space-any, except HB-701, HB-702 which are established only by paws downwards.
The connecting sizes of limit switches of the KU-700, HB-700, VU-700 series fully correspond to the sizes of switches of the KU-700A, HB-700 A, VU-700 A series made in Uzbekistan.
