The Datsun 1200 ignition switch is also known as an "Ignition Starter Switch". For Japan STD and DX models, it is integrated into the Key lock switch. For USA, it bolts to the back of the key cylinder.
Contents |
Japan
STD and DX 1200s built for Japan market have a dash-mounted switch (instead of steering column-mounted). The lock & ignition switch are integrated with only two or three spade terminals on the switch.
See Keys
GL and GX models use same/similar to USA ignition switch.
North America
For USA, the ignition switch bolts to the back of the key cylinder. A a rectangular wire connector from the dash harness attaches to it. It is not strictly part of the Key lock & barrel, but bolts to it.
Fitment
Lock Comparison - No ACC position for 1971, which uses a different ignition switch.

Interchange
Ignition Switch Comparison
- B110 Small size ~28mm diameter
- B310 Large size ~34mm diameter. Also used by newer B110
- The long-wired switch may be B210? It looks like it would plug into the Small B110 harness, but is wired differently. Beware!
The larger-diameter switch has two mounting lugs and is used with Keylocks that have an ACC position. 1972 and 1973 1200s use this.
The small-diameter switch has one bolting lug. It was used on 1971 B110 (and any without ACC position).
ACDelco E1406 ignition switch also fits:
- 1970-1973 Datsun 240Z
- 1971 Datsun 510

Wiring
The 1971 switch has four spade terminals. The 1972 and newer adds the "Accessory" position and so has five spade terminals.
The two wires at the front of the Lock Cylinder are for the Warning Buzzer system.
TIP: On the back of the switch, each contact is marked ('S', 'IG', etc.). Double-check before replacing to ensure they are the same.
| W | B (Battery) |
| BW or | IG (ignition/Run) |
| BW (LW for B210) | ACC (Accessory)
1971 switches didn't have ACC position |
| BY (YB for B210) | S (start) |
| BR | R (resistor) |
The switch in the picture with the wires has differently colored wires (WR, L, BL, BW, BY). From these colors and position, I think it is the same wiring as the B310 switch, just different colors.
Switch
Switch internal connections| Off | no connections |
| Accessory | Battery (hot) to ACC |
| Run | Battery (hot) to ACC + IG |
| Start | Battery (hot) to IG + Resistor + Start\* |
| switch terminal | Connects to ... |
| IG (ignition/run) | This connects to two things:
|
| S (start) |
On automatic cars*, this goes through the "Nuetral Switch". |
| B (battery/hot) |
|
| R (resistor) |
|
| ACC (accessory) |

Common Problems
Ever had the "sometime it doesn't start until I turn the key back and forth a few times" problem?
This occurs because the relatively high current loads of the starter solenoid tend to burn the ignition switch Start contacts after some years. This only gets worse. You might think you could prevent this problem by using a relay. The S wire could go to to a relay, and the relay could go from the Main Fuse to the starter. The problem is if the relay sticks, you won't be able to turn it off with the key. To prevent this, you could use two relays, with the main power fed through a relay connected to the IG terminal of the switch. Then if the starter relay sticks, you could turn key to ACC or OFF to stop it.
It is easiest just to replace the switch.
