Dimensions and Design:

• Compact design with detailed measurements for panel cutout and mounting.

• Available configurations: single unit up to 10 units.

Coding System (8421C):

• Operation Logic:

  • When a number is dialed (0-9), specific connections occur between the C terminal (common) and numbered terminals (1, 2, 4, 8).

  • Example:

    • For 1, C and 1 are connected.

    • For 3, C and terminals 1 + 2 are connected.

    • For 9, C and terminals 1 + 8 are connected.

SPDT Repeating Function:

• 10-position switch alternating between plus (+) and minus (-) connections.

Applications:
Ideal for digital coding, industrial control, and electronic circuits requiring reliable toggle switches with multiple contacts and BCD output.
