Could anyone advise me on the correct wiring between a dapol signal and a Peco passing contact lever switch which has been fitted into a module with three outputs please? The signal has four wires, two yellow which are the switch wires and red and black wires for the constant power source.

Ignore what I wrote as I assumed that they were solenoid machines and they are not. The item in the picture holds a switch and is not a switch the in itself.
I've not actually bought a Dapol signal or one of those switch cases.
I'm guessing here. The four wires from the signal are from two coils of a solenoid. It seems to me that the two the same colour can be used as the common. The other two wires will be for the one direction or the other direction of the passing contact switch.
I'm assuming the Dapol signal works via solenoids here, and I've made a guard as to the two wires that are the same colour would be the common.

Thanks
I have only showed the
housing for the switch as this has the three holes for the wires
I do have the switch that fits into it
So I assume the red and black wires go in the outer two holes and the two
yellow wires go in the centre hole?

AFAIK passing contact switches are not suitable for the Dapol signals. They will work after a fashion but aren't the right sort of switch for the job. What would work is a push to make switch. Each time the switch is operated the signal moves both to the on and then on the next operation to the off position.

Do not under any circumstances connect power to the switch wires from the signal as it will damage the signal.

Out of interest as I've not seen these Dapol signals other then a few pictures. Are they solenoid or motor mechanised, or are they servo driven?

They have tiny motor inside them with a special control PCB.

Thanks for that Roger. I assumed they were made in the traditional solenoid way. I've given him a PM to look at the link you put up.

You can use a passing contact switch (people have done it and appear to have results as good as can be expected) - connect one of the yellow wires to the switch common, and connect the other yellow wire to both of the other terminals on the passing contact switch. Black and red leads from the signal should go to a 9V DC power supply.

You might have synch problems from time to time where the action of the switch will be reversed - but this is a feature of the poor design of the Dapol signal.
