## Description

Product Description Bosch has been producing relays for vehicles and other applications for more than 40 years - this vast development experience ensures continuous advancement in design features to deliver optimum performance. Bosch Mini Relays feature a compact design and are used in a wide range of vehicles to perform switching operations. Bosch relays incorporate only the highest quality materials for reliable, long-term performance and a 250,000 switching cycle capability. Engineered with high corrosion resistance to ensure long term reliability in harsh environments and conditions. 5 pins, 12V, 20/30A. Integral bracket mount. Black. Set Contains: 5 Pins, 12 V, 20/30 A, black Changeover Mini Relays with a bracket

Review: Relay works as expected--switches between 87 and 87a contacts - This is a normally open, single pole, double throw relay. That means when you apply voltage to the 85 and 86 relays, the relay switches from normally open to closed. In terms of actual contacts, when the relay is not active (there is no voltage between 85 and 86), relay 87 (NO) is not connected to relay 30 (Common). However, 87a (NC) IS connected to relay 30 when there is no voltage. When the relay IS active (there IS voltage between 85 and 86), relay 87 (NO) IS connected to relay 30 (common), and relay 87a (NC) IS NOT connected to relay 30 (common). Note: You will hear an audible click when the relay becomes active, and another click when the relay becomes inactive. This relay has no diode, so you can apply the positive voltage to either the 85 or 86 contact.
Review: great price - good fix

## Questions & Answers

**Q: There are various picture.. does this item have mounting tab/hole?**
A: The one I received had a mounting hole. They normally do

**Q: Can this relay be used on the exterior of a vehicle? (Between the frame rails of a truck)**
A: yes, but water can short between the terminals so... mount with terminals pointed down and in a heavy plastic bag with a drain tube under-neath?

**Q: Will this relay fuse work for fass lift pump or is it for flashers**
A: It’s not a fuse. It’s a relay. And yes a flasher is a relay that goes on and off. This is an actual relay. As long as the amps don’t exceed the rated relay amps your good. But being a pump I’m guessing the amperage ( in rush on startup) might exceed this relay. I’m which case you’ll need a contacter
