Hi,

Just wanted to better understand this relay.

Will this relay only give 12v momentary output once its de-energised?

It gives a 1/2 second pulse when negative is applied to the "switch" part of the diagram.

Hi, sorry just a stupid question. So whenever negative is applied, it will give short negative output? If the applied negative is constant then it will still give short negative output? Doesn't matter how long the applied negative is?
