Original BMW Ignition Switch for BMW E34 5 Series and E32 7 Series (1990–1995)

On the E34 5 Series and E32 7 Series, Original BMW ignition switch 61-32-8-356-025 is the electrical switch that sends power to the accessories, the ignition system, and the starter as the key turns. It works together with the ignition lock cylinder. Each key position, from Off through Accessory and On to Start, feeds a different group of vehicle functions. BMW has produced this switch since January 1991, and it is made in Germany. The unit weighs 105 grams and is sold as a single switch.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier switch 61-32-8-356-026, and BMW rates the two as bilaterally exchangeable, so either one can be fitted in place of the other. That matters because the number on the switch in your car may be either version. The same switch appears across a wide spread of engines in BMW's parts data. In the E34 that includes the M20 and M50 six-cylinders in the 525i, the M30 in the 535i, the M60 V8 in the 530i and 540i, and the S38 in the M5 3.6. In the E32 it covers the M30 in the 735i and 735iL, the M60 in the 740i and 740iL, and the M70 V12 in the 750iL. Engine choice does not change the switch.

Common Questions

My car has 61-32-8-356-026. Can I use this switch?
Yes. BMW rates the two numbers as bilaterally exchangeable, so this switch replaces the earlier one directly.

What symptoms point to a failing ignition switch?
The engine may fail to start or crank only intermittently because the switch is not reliably supplying power to the starter or ignition system. Accessories such as the radio, headlights, or power windows may also quit or shut off unexpectedly with the key in On or Accessory.
