Single pole switch with 3 black wires
I am replacing my single pole light switch and noticed when I removed the old switch that there are three black wires coming from the box. All the white wires are capped together and the same is for the ground wires. Of the three black wires, only one of them is hot. I've identified the one that is hot, the one that leads to the light and the other one is the one that continues the load.
When I connect the hot and the feed wires with pigtail to one screw and the light black to the other screw. When I turn on the circuit, it trips.
Can't seem to get things right.
I am not very experienced with electrical. Could it be that the light is wired incorrectly?

no.. If I connect the Hot black wire and the other wire, to the switch, it is controlling the load that feeds the bath and other lights down the line. The circuit doesn't trip when I have jsut those two wires on the switch (or jsut capped together.
Anytime that I tried to add what I believe is for the light, the circuit trips..

I think you disconnected and reconnected the whites, correct?
It sounds like you bundled a white wire with the other whites that isn't supposed to be there.
Do you remember doing this??

so there was a dimer switch that broke that I was just replacing,.. The white wires (all three) were capped together (I didn't touch them). I was able to ID the 3 black wires but now lost....

Let's go back to the beginning. What was the reason for replacing the switch, in the first place? What happens if you reinstall the old switch or even a third switch?
Edit: Never mind, I see the answer to that.
Secondly, what are the "other lights down the line"? Are they only controlled by that switch?
Lastly, it doesn't matter if both terminals are on the same side or not. There is an input & an output. It doesn't matter which terminal is used, for the input.
Edit: Something just occurred to me. The third wire got damaged while changing the switch & there is a dead short somewhere.

I'm sorry also. Ray already gave you the answer. It sounds like you don't know what a pigtail is.
Connect the black to light to one switch terminal. The Hot and the black that provides power downstream: Connect them together with a 6 - 8" piece of black wire. Connect this one pigtail to other switch terminal.

the switch that I am changing controls a single light over kitchen table. it doesn't control anything else. If the hot the other line (not the light) are not connected, then the light in bath room as well as hall light do not work..

When I connect the hot and the feed wires with pigtail to one screw and the light black to the other screw. When I turn on the circuit, it trips.

It certainly sounds like power in, power out and the switched hot. Does the breaker trip with the switch out of the box?
