Wiring and componentsQuestion 412 of 1506

Why is a switch connected in series with a load?

  1. Opening the switch breaks the only path and de-energizes the load
  2. It keeps the load at a lower voltage than the supply
  3. It lets the load operate when the switch is open
  4. It increases the current through the load
Show answer

Correct answer: Opening the switch breaks the only path and de-energizes the load

A series switch interrupts the single current path.
