western Posted June 26, 2012 Share Posted June 26, 2012 I'll find out when it gets powered up. Quote Link to comment Share on other sites More sharing options...
western Posted June 26, 2012 Share Posted June 26, 2012 PaulMc -- when the new switch arrives, I'll post a photo/diagram of it's connections. also on a elctrically related subject are you able obtain or know where I can get the treminals/plug for the 300tdi/td5 type interior lights IIRC the part number is YPC10028 Quote Link to comment Share on other sites More sharing options...

A lot of suppliers will refer you to the dimensionally similar Sumitomo MTW .110" (2.8mm) connector/terminal, as an equivalent, but I'm not sure if it will fit the interior light - I will investigate and let you know. .

western Posted June 27, 2012 Share Posted June 27, 2012 I started doing a diagram of switch connections, then thought that it might be better to wait and see what switch you had I think that's a great idea, it's a SWF 511 momentary.haven't got a terminal diagram for it yet. not to wory about the interior light plug, they work OK, just wanted to know if the corect item was easily available, seems like it's a bit rare, so I'll leave the existing spade terminals as they are.

western Posted July 9, 2012 Share Posted July 9, 2012 got my momentary switch oday, it has 2 terminals in positions 1 & 5 looking at terminal face of the switch they are numbered 1 - 2 3 - 4 5 - 6 7 - 8 odd numbers on left as I'm looking at the terminals off position [posn.] is rocker upper end in & on posn. rocker lower end spring loaded - makes contact & returns to off posn. switch on indication light is 2 seperate terminals Quote Link to comment Share on other sites More sharing options...

Do you have a SWF Britax part number? . Quote Link to comment Share on other sites More sharing options...
western Posted July 9, 2012 Share Posted July 9, 2012 no diagram. just the switch part number stamped in body is 511- 007 Quote Link to comment Share on other sites More sharing options...
PaulMc Posted July 9, 2012 Share Posted July 9, 2012 According to my Britax catalogue, 511-007 is a non illuminated, non-latching, single pole on/off switch. It switches across terminals 1 and 5 I did a Google search for SWF 511-007, and came up with this image from the Hella catalogue (same as from my Britax catalogue) - (Britax 511-007 is the same as Hella 6GM 004 570-051) .

western Posted July 9, 2012 Share Posted July 9, 2012 there wasn't a illumination bulb/holder with it but it does have the facility for illumination, I have the bulb/holder from the plain on/off latching switch & the front heated screen lens, now swapped to the new momentary switch. so on my circuit diagram, I feed the switch from timer terminal 8 & send other side to earth & switch the warning light from timer terminal 5 & other side to earth.?

Timer terminal 8 is connected to terminal 85 on the power relay and one terminal of the switch's warning light (other warning light terminal goes to earth). Timer terminal 5 goes to terminal 1 (or 5) on the switch, with the other terminal to earth. So that - When you press the switch, terminal 5 of the timer relay is earthed momentarily and the timed period starts. During this timed period, the timer relay's output triggers the power relay and lights the switch's warning light. . Quote Link to comment Share on other sites More sharing options...
western Posted July 9, 2012 Share Posted July 9, 2012 Excellent, Thanks very much for that confirmation. I've printed the switch circuit diagram you added & have made the notes above to it. next step is to join all the parts together. Quote Link to comment Share on other sites More sharing options...

western Posted September 8, 2012 Share Posted September 8, 2012 Well nearly 3 months on & today I've been fitting the relays, routing the wiring & some connections done, just 5 more connections to make & my heated screen should be working.

western Posted September 9, 2012 Share Posted September 9, 2012 all the wiring is connected but I think the timer unit is duff. no light in switch when the switch is operated & yes it's wired to only function when engine is running. Quote Link to comment Share on other sites More sharing options...
western Posted September 16, 2012 Share Posted September 16, 2012 revised wiring diagram, will it function ??? Quote Link to comment Share on other sites More sharing options...
PaulMc Posted September 16, 2012 Share Posted September 16, 2012 Ralph, The PG wire from terminal 85 of the 70A relay should go to terminal 8 on the timer relay. So that, when the timer is in it's timed period and is energising the coil of the 70A relay, it's also lighting the switch's warning light. Other than that, the diagram looks fine .

western Posted September 16, 2012 Share Posted September 16, 2012 Thanks Paul, I can swap those wires over without to much trouble. when I've got it all operational, a new final diagram will be posted. I'm not sure the 70amp relay is working so I've a new one on the way. Quote Link to comment Share on other sites More sharing options...

western Posted September 18, 2012 Share Posted September 18, 2012 cheers Bill, you've used a different timer from mine, got a new 70amp relay coming, so I'll do the alteration that Paul mentioned & see what happens with the new relay.

western Posted September 21, 2012 Share Posted September 21, 2012 my new 70amp relay has arrived, so hopefully weather permitting I can get the wiring completed in line with PaulMc's amendment noted above. how would you test the timer unit ? We tried at work but couldn't get the timer part to latch in for more than 2 seconds, I assume it's meant to latch in for much longer to keep the 70amp relay energised Quote Link to comment Share on other sites More sharing options...
western Posted September 22, 2012 Share Posted September 22, 2012 new 70amp relay fitted & the wiring adjustment made, switched on & tested, all working as it should even the timer 8 minutes operates correctly,Thank you very much to all who assisted with this little project it's only taken me nearly 8 years to complete The final wiring diagram [as fitted to my 1989 110CSW] attached.
