The Datsun 1200 ignition switch is also known as an "Ignition Starter Switch". For STD models, it is integrated into the Key lock switch. For Super DX and higher grades, it bolts to the back of the key cylinder.

Variations

5-position switch vs 4-position switch:
Note addition of ACC position.
Portugal market:
Interruptor de ignićāo [Ignition switch] Desligado [OFF] Ligado [ON] Arranque [START]
Standard Type
STD 1200s and DX built for Japan market have a dash-mounted switch instead of steering column-mounted (Steering Lock). The keylock & ignition switch are integrated with only three or four spade terminals on the switch.
The ignition switch is mounted via bracket on the dash.
The key lock cylinder and ignition switch are integrated in one unit.
NOTE: Early units had a 3-connector ignition switch. Later units had four connectors.

Steering Lock Type
A locking steering column was a Datsun 1200 OPTION for early STD and DX models. It was standard equipment for USA 1200s, JDM GL and GX, and newer JDM 1200 pickups
The actual electrical Ignition Switch for this type is removable, and bolts to the back of the key cylinder. In other words, the Ignition Switch is not strictly part of the Lock Cylinder, but connects to it. A rectangular wire connector from the dash harness attaches to the ignition switch.

Interchange
Later 1200 switches interchange with Datsun B310 and several other Datsun models, but not B210.
Ignition Switch Comparison
* B110 Small size ~28mm diameter
* B110 Large size ~34mm diameter
TIP: On the back of the switch, each contact is marked ('S', 'IG', etc. molded into the plastic). Double-check before replacing to ensure they are the same.
The larger-diameter switch has two mounting lugs and is used with Keylocks that have an ACC position. 1972 and 1973 1200s use this, all the way up to 1982 B310.
The small-diameter switch has one bolting lug. And has only four spade terminals without ACC position. It was used on Japan 1200s (USA only for 1971).

Wiring
The 1971 switch has four spade terminals. The 1972 and newer adds the "Accessory" position and so has five spade terminals.
NOTE: The two wires at the front of the Lock Cylinder are for the Key Warning Buzzer system.
| ACC Position |
|---|
Since 1971 didn't get ACC position, 1971 radios connect to Fuse Box 'L' wire (meaning radio can be operated with key OFF)
| Position | Internal Connection | |

| Off/Garage | no connections | |
| Lock | no connections, column locked | |
| Accessory | Battery to ACC | |
| Run | Battery to ACC + IG | |

Common Problems
Start Problems
Ever had the "sometime it doesn't operate the Starter 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.
Another common issue is when the key is turned to the 'start' position, and it does not spring back to the 'on' position when the key is released. The switch needs to be replaced in this situation also.
Starts but does not Run
"It will crank and catch fire when key turned to Start, but dies as soon as I release the key to the ON position"
The coil is getting Start current, but not Run current. Causes may include:
- Ballast Resistor is burned open. It is only use to Run, but not to Start
- Wiring is loose or bad on ballast resistor
- Ignition Switch is bad. START position works, but ON does not
Testing
You can test the ignition switch with an ohmmter, which is the most direct way. A test light will work too but needs a voltage feed.
- Pull the wiring connector off the back of the ignition switch
- Unscrew the ignition switch from bracket (early/STD 1200s) or rear of the key lock cylinder (Steering Lock 1200s)
- Check ohms between S and B terminals. Should be infinite ohms (no reading)
Turn switch with screwdriver to Start and hold it there. Ohms between S and B should be 0 ohms. If it does not test out correctly, get another ignition switch.
