You need to switch between two loads on the same circuit – a high and low horn, or fog lamps that changeover with your headlights. This Jaycar SPDT relay handles that in a 22 × 15 mm package. 12 V DC coil, 30 A contacts, single-pole double-throw. One relay does the changeover so you're not wiring two separate switches into the same loom
