DISTRIBUTION DEVICE Russian patent published in 2015 - IPC H01H71/00 H01H71/52 

FIELD: electricity.

SUBSTANCE: distribution device with an insulating body comprises movable contacts supported by the first end of at least two contact levers respectively. Each contact lever is mounted around a turning pin (21) supported by a support arm of the working mechanism thus ensuring at least turn-out of contact levers into position of contacts closure. The device also comprises a contact-pressing device, which contains two torsional springs (31, 32) acting independently on each of contact levers. Each torsional spring is placed around a contact lever on which it acts so that the axis of spring rotation is shifted in direction of the second end of the contact lever in regard to the turning pin axis.

EFFECT: limited movement of contact levers at turning of the support arm into position of contact closure with potential optimisation for selected dimensions and placement of the contact-pressing spring.
