This is for the younger crowd that has never adventured into an electric furnace.
First pic shows one side of the electrical terminal that connects to the heating element where I take the amp readings at. Second pic shows the electrical sequencer that is activated by the thermostat to bring on the heat mode. This sequencer is older than dirt as a matter of fact have not observed any other sequencers that had this physical shape. Third Pic shows the heating element. Nichrome wire strung on ceramic insulators.

Boy, that brings back memories! I used to replace a lot of those components 'back in the day'. Kinda wish I had pics of all the different types of sequencers used by the manufacturers back then. And restringing those elements is a real art!
