Description
Overview:
The Durite Relay Micro Change Over 20/30A 12V with Diode (Pack of 10) is a compact, genuine automotive-style relay designed for reliable control of medium-load circuits on 12V systems. Housed in a tough black thermoplastic body with five metal blade terminals, it provides single pole, double throw (SPDT) changeover switching in a micro footprint that fits neatly into relay sockets and tight control boxes. The integrated suppression diode protects upstream electronics from coil back-EMF, so coil polarity must be observed during installation. With a 20/30A load rating, it is suitable for switching pumps, fans, lighting, beacons, and solenoids on vehicles, plant, construction equipment, agricultural machinery, and garden machinery. Supplied as a pack of 10 for workshops, fleets, and service kits.
Key Features:
- Genuine Durite micro changeover relay (SPDT) for dependable switching on 12V systems
- 20/30A load rating for robust control of medium-current circuits
- Integrated flyback diode for surge suppression; polarity sensitive coil for correct installation
- Compact micro form factor for easy integration in crowded fuse/relay boxes
- Durable black thermoplastic housing with metal blade terminals for secure connections
- 5-pin layout supports both normally open and normally closed outputs for flexible wiring
- Compatible with standard automotive relay sockets and harnesses to speed up fitting
- Stable switching performance suited to frequent on/off duty cycles
- Supplied in a pack of 10 to cover multiple repairs or builds
- Suitable for trades, workshops, and DIY users needing reliable power control
Typical Applications:
Powering and isolating loads such as radiator and HVAC fans, fuel and water pumps, work lights and beacons, horn circuits, heaters, clutch or valve solenoids, and auxiliary accessories on cars, vans, 4x4s, trailers, agricultural kit, plant and construction machinery, and garden machinery. Ideal where compact size and diode suppression are required to protect ECUs and switches.
