Operations of drum switch:

The structure and operations of the given drum switch is as follows:

  • To operate the contact blocks in the drum, the “pegs” are situated at the particular locations around the drum.
  • The contacts which are associated with the “pegs” are closed and the contacts without pegs are opened when the drum gets rotated.
  • The logical value “1” or “ON” is used to represent the peg existence and the logical value “0” or “OFF” is used to represent the peg non-existence.

Sequencer data table:

The equivalent sequencer data table for the four steps of the mechanical drum-operated sequence is as follows:
