Block-contact MP-3 for VNA KEAZ 291821

MP-3 type block contacts are used to signal the positions ("on", "off", "grounded") of VNA load break switches. They provide the necessary switching in the control circuit and often function as a sensor providing a light or sound signal. Block contacts are installed on the shaft of the current-carrying and (or) grounding knife shafts. They consist of a switching cam, a bracket, and a set of microswitches (up to 3 pieces). Each microswitch has one normally closed and one normally open contact. Application area: automatic device circuits, interlocking, signaling, control, indication, etc.
