In OR circuits, all devices are connected in parallel. The white lamp (C9) lights up when at least one of BS1 or BS2 is closed. This is called "OR circuit" because the white lamp lights up under the condition of BS1 "or" BS2.

Devices to use

  • Circuit breaker
  • Red lamp (C2)
  • Fuse (enclosed type, 5 A) 
  • Terminal block
  • Switch 1 (BS1)
