Hi,
I just replaced my sensor panel & the wiring was a bit updated on the panel itself, however I need guidance on the water pump wiring as follows:

Water pump switch in sensor panel & another in bathroom.
The 2 wires from the bathroom switch have 1 hot, 1 not (on/off).
The sensor panel switch is hard wired to power, ground.
The single water pump wire is at the sensor panel with the other 2 switch wires.

I can connect each switch up individually to the pump wire & everything works as it should with single switch.

I can connect both switches up to the pump wire EXCEPT the bathroom switch HOT wire (HOT is determined by switch on/off position) and boht switches will work independently just fine.

SO, the HOT wire from bathroom switch, where would that typically be run to?

Or is the question where does each wire from the bathroom pump switch get wired to (1 HOT, 1 NOT) at the sensor panel switch & single pump wire?

I have pictures if needed to further help with visual, however any assistance on where to ensure the wiring is setup correctly is much appreciated.

Make and model of rig would be beneficial.
Are the switches momentary or are they on/off type?
Momentary usually go to a pump controller.

The Sensor Monitor Panel M25 | KIB Replacement is what I put in (Amazon link below)
They are on/off switches

It's the same basic idea as a 3 way switch for a light in a house that's controlled from two (or more) switches. The two switches are both SPDT switches--single pole, double throw. One of the switches connects the common terminal to power, and then the other two terminals go to two wires to the other switch. That switch has the common terminal connected to the pump. The ground from the pump to the system ground completes the circuit.

If both swtiches are set to the same one of the two wires between them, the circuit is on and power flows to the pump. Flipping either switch will have them connected to different wires and open the circuit; and then flipping the other one (or filipping the first one back) will again turn the circuit back on.

If you want to add one or more additional switches, you put them in between the existing switches (electrically speaking). These additional switches need to be DPDT swtiches--double pole, double throw--and wired criss-crossed so as to either reverse the two wires or not depending on how they are thrown. That's what the linked diagram was trying to show.

If the monitor panel has a pilot light indicating the pump is on, then it's the switch that's wired to the pump, and the bathroom one is the one wired to the positive power supply (which may in turn come from...well, most anywhere, possibly including the monitor panel). The reason for this is that the pilot light is wired in parallel with the pump so it can illuminate when the pump is on.

Thank You.
So the new panel has the indicator light built into the panel pump switch where as the old panel had a separate dedicated indicator light.

I am attaching some pics.

Currently both switches in off position have a power source (the panel switch to panel & bath switch well from somewhere as you mentioned.

So if reading correctly, I think the pwr side of the bathroom switch when in off position, needs to be connected to the panel switch power wire to supply the panel switch power vs. the panel switch getting power from the panel directly which of course I would cut from its current power source at panel.

Sound right?

See if this helps.
Four switch diagram
This type different type of switches then just two wire.

This is resolved.. TY
The panel assumes a single switch to pump. I simply used the power from the 2nd bathroom switch to supply the panel switch instead of using panel power & then connected so each switch operates independently.
