Standard Ignition Ignition Switch P/N:US-694
Standard Motor Products
Standard Ignition US-939 switch for the 1997 BMW 528i and other vehicles is an electrically operated ignition starter switch. If a damaged switch is the cause of your ignition problem, this direct-fit unit replaces it and is made to OE spec for fit, form and function.
A key that turns roughly, an engine that does not crank or flickering dash lights can point to a worn switch. A weak battery, a tired starter or a damaged key can be behind the same signs, so find the cause before buying.
This switch fits the 1997 BMW 528i and the 1997 BMW 540i, and both take one.
