How To Take Apart A Microwave

Step 13 Power relay and light bulb

You can use the relay for heavy load switching and if the light bulb still works, you can save it as an replacement bulb for other microwaves.

What is a relay and how do you hook it up? Is it like a switch?

An relay is an high power electronic switch. Relays have many different configurations, I suggest looking at the relay's datasheet to hook it up properly.

most relays you can find for cheap are usually in tv's because of the high voltages. you can here the turn on when you hit the "on" button ( you would here a click noise). the actual connetion can handle a lot more than an actual switch of the same or smaller size.

ive seen videos of a lightbulb in a microwave and they glow verry brightly and then explode. what do they do to make sure the light that comes with the microwave does not explode?

The whole microwave is shielded against radiation, the magnetron feeds directly into the chamber. The light bulb is never exposed to radiation.
