Standard/mini change over relay rated at 12V, 30/40A. Features a diode fitted across the coil (terminals 85 & 86) to suppress voltage spikes that occur in the coil circuit when the relay is de-energised. If not suppressed these can damage sensitive circuit components such as found in central locking or alarm systems.

Important: +12V must be applied to terminal 86 and ground to terminal 85. If this is reversed the diode may be damaged.

Sold individually.

Found a lot of good advice on the website, which I hadn't expected, this proved very useful and ensured I was able to place my order with confidence. Pricing very fair and delivery prompt!
