🔍 Key Concepts

• Drum-type motor controller construction and purpose • Role of movable contacts versus fixed contacts • How motor starting and speed control are achieved in older controller designs

💭 Think About

• Think about what physically happens when you rotate the drum handle and the movable contacts sweep over different contact segments—what changes in the motor circuit? • Ask yourself: do the movable contacts themselves clean, insulate, or limit load, or do they mainly open/close and rearrange parts of the circuit? • Which option best matches the idea of connecting different parts of the power circuit or resistor banks in sequence as the drum is moved?

✅ Before You Answer

• Identify which choice describes a switching or connecting function rather than a protective or cleaning function. • Eliminate any options that sound like secondary effects rather than the primary job of a contact in a controller. • Confirm that your chosen option directly relates to controlling what the motor sees electrically as the handle moves through its positions.
