STEP3 AND Circuit

Question

Turn on the white lamp only when pressing BS1 (switch 1) and BS2 (switch 2) at a time.

AND Circuit (multiplication)

1: ON state
0: OFF state

In an AND circuit, multiple switches are connected in series.
When both BS1 and BS2 are closed, the white lamp (C9) lights up. This is called “AND circuit” because the white lamp lights up under the condition of BS1 “and” BS2.

Devices to use

  • Circuit breaker
  • Red lamp (C2)
  • Fuse (enclosed type, 5 A)
  • Terminal block
  • Switch 1 (BS1)
  • Switch 2 (BS2)
  • White lamp (C9)
