High quality micro 'change over' relay. Features a diode fitted across the coil (terminals 1 & 2) 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.

Rated at 12V, 12/25A.  Terminals are 3 x 4.8mm and 2 x 6.3mm blades.

Can also be used as a 4 pin relay simply by leaving one of the output terminals disconnected.

Important: +12V must be applied to terminal 1 and ground to terminal 2. If this is reversed the diode may be damaged.

Sold individually.


  • Voltage rating: 12V DC

Further information

The dual current rating (15/25A) means that the output connected when the coil is not energised (terminal 4 - 4.8mm) can carry 15A , and the output connected when the coil is energised (terminal 5 - 6.3mm) can carry 25A.
