This switch plays a significant role in the engine's ignition and vacuum systems, ensuring optimal performance under various operating conditions.
This Delco part is a vacuum control switch designed specifically for use in General Motors (GM) engines.

By monitoring the vacuum level, the switch allows the engine to adjust ignition timing for improved fuel efficiency and smoother operation.

The switch is designed with a durable construction, featuring a compact, yet functional design, making it a perfect fit for the specified Cadillac models.
The switch has a vacuum actuator that responds to changes in vacuum pressure in the intake manifold.
