    On a car, I get an alarm when the rear hatch is ajar. I want to be able to manipulate that switch to show it is ajar, even though the hatch is closed.
    Can I hook up a N/O contact to the rear hatch ajar switch, then use a 1.5 DC volt source to close that N/O contact to operate the rear hatch ajar switch. If so, will it harm the 1.5 DC volt circuit?

    Unfortunately while your question is simple in nature it does violate this forum's rules as to automotive modifications. Not trying to memberate just letting you know. A kind moderator will likely suggest another forum and explain the rules here.
