Mr. Babin,

Conditions: Input .5 Vac, 60hz tone applied, pin Vac are as follows.

Pin 1= .069
Pin 2= 1.01
Pin 3= 1.50
Pin 4= .93
Pin 5= .12
Pin 6= .13
Pin 7= 1.51
Pin 8= .14
Pin 9= .18
Pin 10= 1.50
Pin 11= .98
Pin 12= .92
Pin 13= .92
Pin 14= .74

I hope this makes more sense than before.
Thank you.

Did not find an exact match datasheet for the switch. However I did take readings. No power applied, and I used the following pin layout;
1 8
2 7
3 6

4 5
So with phase switched to 0 these were the pin readings:

Pin 1 = 0 ohms to 3,6,8 / 19.9 kohms to 7/ speratic to 4

Pin 2 = no readings

Pin 3 = 0 ohms to 1,6,8 / 19.9 kohms to 7 / speratic to 4

Pin 4 = speratic to 1,3,6,7,8

Pin 5 = no readings

Pin 6 = 0 ohms to 1,3,8 / 19.9 kohms to 7 / speratic to 4

Pin 7 = 19.9 kohms to 1,3,6,8 / speratic to 4

Pin 8 = 0 ohms to 1,3,6 / 19.9 kohms to 7 / speratic to 4

Phase switch set to 180:

Pin 1 = no readings

Pin 2 = 0ohms to 3,6,7 / 19.9 kohms to 8 / speratic to 4

Pin 3 = 0 ohms to 2,6,7 / 19.9 kohms to 8 / speratic to 4

Pin 4 = speratic to 2,3,6,7,8

Pin 5 = no readings

Pin 6 = 0 ohms to 2,3,7 / 19.9 kohms to 8 / speratic to 4

Pin 7 = 0 ohms to 2,3,6 / 19.9 kohms to 8 / speratic to 4

Pin 8 = 19.9 kohms to 2,3,6,7 / speratic to 4

I hope I wrote this for your easy of reading, it is alot of info for a little switch.
Thank you for your time.

The attached image shows a switch that's similar to the one you have. Do you see continuity between the contacts shorted by the movable contact in each of the 3 positions.

OK.

Are you sure that that's the phase switch? I would expect the phase switch to have only 2 positions.

The voltages you posted for the stereo settings seem about right. Set the amp to mono and check the H and W pins listed previously. Confirm that they're the same in stereo as previously then do nothing but change the position of the switch you checked and see how the readings change.

Yes, I am sure.

The right channel switch is for 0 phase, 180 phase, and the last position is Mono Bridged.

Now the left pase switch only has two positions 0 phase and 180 phase.

As for the test, I just want to make sure, you want me to test the voltage on the DS1267? If so I will use .5Vac input and a 60hz tone. To test the H1, H0, W1, and W0 pins.

Thank you for your help.

Mr. Babin,

DS1267 test with right phase switch in mono bridged mode and then in 180 degrees. test was conducted with a 60 Hz tone at .5 Vac input.

Mono Bridged:
H1 = 5.51

W1 = 5.31

H0 = 5.44

W0 =5.28

180 degrees:
H1 = 5.51

W1 = 5.31

H0 = 5.44

W0 = 5.28

The results are the same. I am starting to think that the switch maybe working intermittently, but of course it is working right now. Or possibly a component in the crossover section, since we have isolated that section out. I would have no idea where to start with that.

I do have a new switch I can swap out with the one in question.

Regardless, I will wait for your response, before moving forward. Thank you for your time, and help.
