Description:TECHNICAL FIELD
[0001] The present disclosure relates to switchgear. More particularly the present disclosure relates provide a linkage mechanism between the auxiliary switch and the ring switch of the switchgear.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A typical RMU of the switchgear panel consist of a ring switches & one VCB. The numbers of RSW and VCB can vary according to customer requirements. This ring can be in three positions i.e. On, Off, Earth. The physical position of the ring switch needs to be indicated electrically to remote operator as well as for control of motorized operation of Load Break Switch. Failing to this may cause damage to the maintenance worker.
[0004] For Achieving this, auxiliary switch can be used. An auxiliary switch is a single pole, TRIPLE) throw switch operated by the movable contact arm assembly. It is used to remotely indicate the position of the LBS contacts, whether open, closed or earthed. At the time, this indication is achieved using a part which presses limit switch on rotation of LBS. The use of auxiliary switch and actuating mechanism here is more cost effective and reliable.
[0005] There is, therefore, a need for a linkage mechanism between the auxiliary switch and the ring switch for efficient operation.
