You are correct. With those types of clamps, you simply strip the wire to the correct length (often indicated on the switch itself) and push it straight in under the clamp. No hooks or loops are needed.While many people prefer hooking the wires around screws (often considered a more secure and reliable method, especially for higher current applications), the straight-in clamp connections are perfectly acceptable for many applications and, when done correctly, can be just as safe.Here's a breakdown of why your understanding is correct and some additional points to consider: How They Work

These clamps are designed to grip the stripped wire securely when the screw is tightened. The pressure from the clamp provides the electrical connection.

No Hooks Needed

Attempting to make a hook and wrap it around the screw would actually hinder the connection, as it wouldn't sit properly under the clamp.

Proper Stripping Length



Critically important. If you strip too much, you risk exposed wire. If you strip too little, the clamp won't make proper contact. The switch will often have a gauge to show you how much insulation to strip off. Tightening Torque

Use the correct amount of torque when tightening the screw. Over-tightening can damage the clamp or wire, and under-tightening can lead to a loose connection and potential arcing/heat.

Reasons why you might prefer hooking wires around screws



Perceived Security

Many electricians and homeowners feel that a properly made hook-and-screw connection is more mechanically robust and less prone to loosening over time, especially with vibrations or temperature changes.

Easier to Inspect

A properly hooked wire is easy to visually inspect to ensure a good connection. The clamp type is not visible once the wires are under the clamps.

Reusability

Hooked connections are often easier to undo and redo if you need to move or replace the switch. The clamps will bend the wires and will cause them to be less straight.

Important Safety Note: Always* turn off the power at the circuit breaker before working on any electrical wiring. Use a voltage tester to confirm the power is off before touching any wires. If you're not comfortable working with electricity, consult a qualified electrician. Flag for review
