Narva Universal Door/alarm Switch Contacts Rated 10A 12V Part No. 60042BL

The Narva Universal Door/Alarm Switch is a 12V switch rated at 10A, with a 5A rating at 24V, and it carries Part No. 60042BL. It is a door light style switch with normally closed contacts, non-illuminated operation, and a single push-on terminal arrangement.

This switch uses an extended arm that is suitable for cutting to length, which gives some flexibility during installation where the mounting position or panel depth needs to be matched carefully. The mounting opening is 10.5mm diameter, while the listed mount diameter is 10mm, so the opening size should be checked against the vehicle or panel before fitting.

Narva lists this unit as a 2-position switch with SPST action and 1 pole. The unit weight is 0.01kg, and it is sold each, which makes it a practical replacement or universal-fit electrical accessory where the existing door or alarm switch design calls for the same style of contact operation.

Application and Buying Notes

Before ordering, confirm the switch style and the space available at the mounting point. This Narva unit uses a 10.5mm diameter mounting opening and a 10mm mount diameter listing, so the panel hole size and physical location matter as much as the electrical rating. The extended arm can be cut to length, which is useful where a universal door or alarm switch needs to be adapted to the vehicle opening.

The electrical side is straightforward but still needs checking. This switch is rated at 10A on 12V systems and 5A on 24V systems, so it should be matched to the circuit requirements rather than assumed to suit every application. It is a normally closed, single pole SPST style switch with one terminal, so the existing wiring and circuit operation should be compared with the replacement part before installation.

For buyers replacing an existing door contact or alarm trigger switch, the most important checks are part number 60042BL, the 12V/10A rating, the 1-terminal arrangement, and whether the application needs a non-illuminated switch with normally closed contacts. If the original switch uses a different terminal count, different action, or a different mounting size, this part may not be a direct replacement.

Because this is a universal-style switch, final suitability depends on the vehicle or equipment application, not just the brand name. Taking a careful look at the hole diameter, arm length, contact type, and circuit rating before fitting will help avoid unnecessary returns and make sure the replacement aligns with the original function.

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 60042BL 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.

Additional published details for cross-checking include Part No. 60042BL, Brand NARVA, Description Narva Universal Door/Alarm Switch (Contacts Rated 10A @ 12V), Number of Terminals 1, Switch Action On - Mom Off - SPST, Lamp Colour/s Not Applicable, Number of Poles 1, Switch Type Door Light, Switch Illumination Non Illuminated.

Narva Universal Door/Alarm Switch (Contacts Rated 10A @ 12V). Part number 60042BL should be checked first. Listed voltage is 12. Listed output rating is 10. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 60042BL, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 10 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Confirm compatibility by checking Part No. 60042BL, the 10A at 12V rating, the 10.5mm mounting opening, the single terminal layout, and the normally closed SPST switch action against the existing application before purchase or installation.
