Dip Switch- Floor Mounted

[Phil H 4]

The innards of my floor mounted dip switch have fallen apart. Whilst I'll try and reassemble for the time being what conversions have members carried out to have the switch dash mounted or controlled by the column stalk.

Thanks Phil

I've seen people put a lhd overdrive housing/switch on and use that.

Thanks Gareth,

Gives me a starting point.

Having now got the switch out can anyone advise is there a correct way to assemble,with referance to the block connector.

Pictures 1  or   Picture 2   or doesn't it matter.

Thanks Phil

I need the two bolts that fix this to the bulkhead, not sure what size I need. 

Any help gratefully received.

The switch looks like it pivots so I'd imagine no.2 so that the common wire connects from the larger contact to either of the top two, depending on where the switch is at, maybe see how the contact inside the body moves when you press the switch to make sure.

Mark,

I'll go and look at mine when the rain stops ! It's a bit of a fiddle getting the nuts on, but gets the wife out of the kitchen

 

The switch pivots both ways. I did look at the connectors on the Moss site but the tabs are different.

Guess if it doesn't work one ways its the other.

I swapped it to the column. Used an overdrive cowl and I think a column light switch from an Austin of some kind.

Personally I would ditch the floor mouted switch as Mk2 Chopper says use an O/D switch or use a latching relay and appropriate diode which can convert your existing headlamp flash into a dipswitch. There are some diagrams in some of the old TRActions but this has been made more complicated by changes to the currently supplied latching relays which have changed in terms of internal wiring

[John Morrison]

See my response in tr4/4a section entitled 'Dipswitch' to

get all the info you will need.

Thanks all, particularly John for the direction to the recent 4/4a post.

Have been looking at using a LHD O/D and Indicator cowl with a bit of adaption and using the O/D stalk to operate the the dip switch.

Will post when functional   should others be thinking of the same conversion.

Regards

Welcome Phil,

just note the O/D switch won't work, you need a momentary switch, my man bought a column one from I think

Car Builder Solutions.

John.

Thanks John,

I'll get the electrical work carried out by DBJ Auto Electrical in Uxbrige, who specialise in vintage and classic car electrics another member put me on to them when I needed some work on the overdrive wiring.

First job will be to see how to join a left handed and a right handed double outlet cowls as in standard form they overlap. I don't think the cowls are expensive so if that works I'll progress with the switches.

Will check out Car Builder Solutions.

If you are going to the expense of having the wiring professionally done consider having two extra relays fitted for high and low beam. 

That way your switches only carry the small coil current and a suitable sized relay will carry the main lighting current, many of us have done this and found an improvement in light output as well as increasing switch life. You may also find it easier to source a suitable switch ,it only needing to have a smaller switching capacity.

Thanks Brian for your advice.

Sorry to contradict the fount of all knowledge TR, but I think they are 2BA not 1/4" unf.

I converted my TR4A from floor mounted Dip switch to column mounted using an extra O/D switch. (See attached diagram).

I found that using the two RH switch cowls works well, and allows space to rotate the switch to suit a push/pull action between dip and main.

The two 1N4007 diodes are for the headlamp flash. They are dirt cheap and easy to hide away under the dash. They have a line at one end that indicates the Cathode.

For Negative earth vehicles, join the Anodes of the diodes together than connect a Cathode to each relay as shown in diagram.

For Positive Earth vehicles reverse each diode. (i.e. join the cathodes together and an anode to each relay)

Good luck

Tony,

Thank you for a most comprehensive diagram.

You said you used two RH cowls, if one is rotated to they connect.

I haven't taken apart as yet but it looks if they are male and female flanges that overlap.
