Goss Air Conditioning Pressure Switch AC123

The GOSS Air Conditioning Pressure Switch, part number AC123, is listed as a pressure switch for cooling and A/C components. It is supplied as each unit and carries a 12 month warranty. For buyers matching an existing switch, the part number and application details are the most important checks before ordering.

GOSS states that its sensors are sourced from OES manufacturers and meet or exceed OE specifications. That matters when you are replacing an air conditioning pressure switch because the correct part needs to suit the vehicle’s A/C system operation and connector/application details, not just the general component type.

This switch is manufactured in Spain and sits in the Product Group 1 Cooling and Product Group 2 AC Components categories. If you are comparing replacement options, AC123 and the GOSS brand identification are the key references to confirm against the vehicle fitment information provided here.

Fitment data supplied with this item references multiple Mercedes-Benz applications, including C-Class, CLK, E-Class, S-Class, SL, Sprinter 3-T, Sprinter 4-T, Valente, Vito / Mixto, and 5-T. As with any pressure switch, the exact vehicle match still needs to be checked carefully against the listed application details before purchase.

Application and Buying Notes

Before ordering a pressure switch, check the part number AC123 against the switch currently fitted to the vehicle. For a component in the A/C system, the safest match is the one confirmed by part number and application details, not by appearance alone.

The supplied fitment data includes Mercedes-Benz applications across multiple model lines, but not every engine, body style, or production year is spelled out in the preview. That means the vehicle model name is only the starting point; the exact year range and application details still need to align with the vehicle being repaired.

This part is listed as a GOSS sensor product and is described as meeting or exceeding OE specifications. That is useful context when replacing a failed switch, but it does not remove the need to confirm connector style, mounting style, and system application before fitting.

Because this is a pressure switch for air conditioning and cooling systems, correct identification matters for system control and protection. If the existing part shows AC123 or matches the listed application, it is still worth checking the original unit and vehicle records before finalising the order.

The item is sold individually as each, so if the vehicle needs more than one related component in the A/C circuit, those other parts must be ordered separately. The 12 month warranty applies to the part as supplied and should be considered alongside the vehicle match check.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number AC123 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For a pressure switches in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 1993. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility by matching part number AC123 and the vehicle application details provided. If the existing switch, connector, or application information does not align, do not assume fitment from the model name alone.
