Rear Window Heater Switch Cap

The OE Match Control Switch Cap is an original-style replacement surround for the rear window heater switch and other compatible dashboard switches fitted to early Porsche 911 models manufactured between 1965 and 1973.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Designed to replace worn, cracked, damaged or missing original switch surrounds, this component helps restore the appearance and finish of the dashboard while maintaining the classic Porsche interior design.

Ideal for classic Porsche restoration projects, the replacement cap allows a damaged or deteriorated switch surround to be renewed without replacing the complete electrical switch assembly.

What Does the Control Switch Cap Do?

The control switch cap fits around the dashboard switch, providing a neat finishing surround and helping maintain the original appearance of the dashboard controls.

It is commonly associated with the rear window heater switch but may also fit other switches using the same mounting arrangement.

Although the cap does not perform an electrical function, it is an important finishing component that contributes to the overall appearance of the dashboard.

Why Does It Fail?

Original dashboard switch caps can deteriorate after decades of use due to ageing, sunlight, heat and repeated handling.

Common causes include:

• Cracking or splitting of the original material
• Age-related brittleness
• Fading or surface deterioration
• Damage during dashboard or switch removal
• Wear around the mounting area
• Missing components following previous repairs

These problems can leave the dashboard looking incomplete or poorly finished.

When Should It Be Replaced?

Replacement is recommended when the original control switch cap becomes cracked, loose, damaged or missing.

Common signs include:

• Visible cracks or splits
• Loose or poorly fitting switch surround
• Deteriorated or discoloured finish
• Damage around the switch mounting area
• Missing cap following dashboard repairs

Replacement is also worthwhile during a dashboard refurbishment or complete classic Porsche interior restoration.

Installation Notes

Carefully remove the original cap without damaging the surrounding dashboard trim or electrical switch.

Inspect the switch mounting area for damage and ensure the replacement cap is correctly positioned and securely fitted.

If the electrical switch itself is faulty, further repair or replacement of the switch assembly may be necessary.

This product is a replacement surround cap only and does not include the complete electrical switch mechanism.
