🔍 Key Concepts

• Look closely at which device is fully enclosed in a case versus those that have exposed contacts or knobs. • A relay that plugs into a pin base (socket) will have a group of round or pin-style terminals arranged to fit a matching socket, not screw or blade lugs. • Consider the difference between a timer module and a simple plug‑in relay; one usually has a dial or time-setting feature on the front.

💭 Think About

• Which of the devices A–D has terminals that look like they are meant to fit into a socket, rather than accept wires directly? • Which device shows the internal relay parts (coil and contacts) inside a protective housing with multiple pins on the bottom? • Which option appears to be designed primarily for timing control, and which appears to be a standard relay body?

✅ Before You Answer

• Verify which illustration has multiple round pins on the bottom arranged in a circle or pattern for a socket base. • Confirm that the device you choose is completely enclosed in a plastic or clear case, not open-frame metal contacts. • Eliminate any device that has screw terminals, spade lugs, or a front-mounted timing dial, since those are not typical of a simple enclosed plug‑in relay.
