Settings for Micro on off switch 2443-222: What do these things mean?

[someguy]

I am trying to use a micro switch to tell me when my driveway heater is heating.  I do NOT want to use it to turn on or off the driveway heating. 

 

I have it wired like it is in "Single Momentary" diagram (attached) but I don't have the "neutral load" wire connected between the module and the load.  

 

I'm trying to understand what would be the best settings to tick in the "Options" box: 

 

"Momentary: (off) Latching".  does this mean latching is off or momentary is off? 

 

"Dual Line: (off) Single line".  similarly confusing.

 

"Line high always on; line low always off: (Off) Act as 3Way".  ditto.

I have no ides what a "neutral load" wire is An electric wire is either neutral, load or line, each mutually exclusive.

 

Leave the box unchecked to be in the mode shown in red. If you are not creating a 3-way configuration, then that option doesn't matter. In general, if you want on responds to On and off responds to Off, then leave all three options unchecked,
