rotary light switch

[neil parsons]

bought one off the bay has 4settings, off-side-dip-beam

 its got numbers on the back off it , anyone know how to wire it up before i have go on the car.

did manage to get all the wiring in , run lots of cables and need  need to

connect to switches and the car is one step being closer to being on the run since 1998

what are the numbers?

a fuller listing and explanation is here...

yes, live feed from ign switched live,  the rest is self explanitary,  sidelight circuit,inc rear lights,  then each of the others to trigger the lighting relays, i would use separate relays for dip and beam, dont forget to add a spur onto the beam  for the warning light,  wire up each circuit one at a time, and test each before adding the next, its quite simple to do,

if the numbers are not clear, 30 i think is live, so fit a wire up to this and earth out your tester, test the switch on 1st setting, to find the live pole, this should be side lights, next dip,  then main beam,  if right, on the first click only the side lights should be live, on the second and third, both headlights and side lights should be live. it can be trial and error  to find the right contacts.

OSCH device connection codes:

**Note: These numbers/letters are found on all sorts of devices in your motorcycle, from sockets to coils. This is a comprehensive list, and it combines Bosch published codes AND the specifications in DIN72552, thus some listings will have 1 or more possible functions/devices. This list covers FAR more than that used on most BMW vehicles. Note that sometimes there is a bit of ambiguity in actual use. The actual total list of all possible connection codes is MUCH longer than on this page. Letters are added to the single or twin numbers to identify particulars.

1 Ignition, coil, primary, breaker, low voltage, distributor
1a If a dual breaker, #1
1b If a dual breaker, #2
2 Ignition, switched ground, magneto
4 Ignition coil, ignition distributor, high voltage
If two circuits, then 4a is coil 1 terminal 4,
and 4 b is coil 2 terminal 4
15 +, primary, ignition coil, ignition switch output
15a output of ignition dropping resistor
17 glow plug of starter switch, start
19 preheat
30 from battery, + direct
30a series parallel switch, 12/24 volts, input, direct, from battery

31 battery negative (-), return line or ground, could be via switch
or relay
32 to 33R all are for series-parallel arrangements of battery 12/24
volt switching, MANY functions.
32 return line, polarity reversed at 32, 33, possible
33 main return
33a self parking switch off
33b shunt field
33f second lower speed
33g third lower speed
33h fourth lower speed
33L CCW rotation
33R CW rotation
45 starter, separate relay, output, main current input
45a 2 starter parallel operation, output 1 and input 1 and 2
45b as above, output 2
48 starter and start repeat relay for monitoring starter
49 turn signal flasher, input
49a turn signal flasher, output
49b turn signal flasher, output, circuit 2
49c turn signal flasher, output, circuit 3
50 starter direct control
50a series-parallel, output of battery switch
50b series-parallel, 2 starters, sequential control
50c input, starter relay 1
50d input, starter relay 2
50e input, starter lock relay
50f output, starter lock relay
51 + to light switch, alternator DC at rectifier.
51e alternator, as above, but with choke coil for day driving
52 trailer signals
53 wiper motor (can have -a,b,c,e,i functions)
54 brake stop light-directional light, trailer items
55 fog lights
56 lights, tach lights, headlights
56a high beam and high beam indicator
56b low beam (d is used for flasher contact)
57 parking light, side markers, -a is parking, L is left, R is right

58 lights...accessory, sidecar, rear. Also used for instruments,
license plate lights, some side markers, and variable
intensity functions
59 alternator a.c....and other functions specialized internally

61 charge light indicator
71 horns
72 alarm, emergency lights
75 radio, cigarette lighter
76 loudspeaker
77 door control

81-88 various styles of switches and relays contacts/connections.
The contacts and coils are identified by letters, typically a, b, c.
Generally, series 81, 82, 83 are normally closed relays; series 87 is normally closed; series 88 is normally open. Terminal 86 a, b and c are assigned to relay coils. Terminals 87, 88 are typically assigned to contact inputs, with letters added for contact outputs, unless 30 is the input, then these are outputs.

D- Alternator/generator negative
D+ Alternator/generator + output
Df Alternator rotor/field.
U, V, and W: Alternator 3 phase connections

B+ Battery +; + on regulator
B- Battery negative (-)

Directional signals:
C First indicator lamp
C2 Second indicator lamp
C3 third lamp
L turn signal, left side
R turn signal, right side

Dave, can I use this on the Northern Duttoneers website?

I found it by a google search so I dont see why not the link in my post above gives the source. Its an American car magazine.
