Relay???

Why can't I just hook one wire to hot and one to the switch / ground.

What kind of relay do I need.

sh*@ I feel dumb. </div></BLOCKQUOTE>

Good question. There's many reasons for relays depending on the task. But here's a simple one that applies. The switches we generally use are very small & just won't handle the current long term without burning up, welding contacts, etc.
If you want to install a large enough switch, no relay works fine.
