Relays. 12V.
Where a heavy current is to be switched
such as a starter solenoid, heated screen,
horn etc, we suggest that you include a
relay to protect the cable and switch.
     
They allow a larger current load to be controlled by a lighter current switch at the facia.
Also reduces voltage drop due to long cables and connections.
Relays with 4 or 5 blade connections conform to EC regulations.

Note that there are two types of terminal layout.
We state the type against each relay
since this is important if replacing a
relay in an existing application.
 

Applications.  
Relay diagrams.
The numbers in brackets refer to the diagrams on the right.
(1) 4 blade. This is the most common relay.
Use for single circuit on/off applications such as
spot lamps, horns, rear screen heater etc.
(2) 4 blade fused. Similar applications to (1),
but these have a replaceable fuse in the
accessory circuit.
(3) 5 blade changeover. Use for applications to
change between two circuits. eg. electric aerials.
(4) 5 blade double make & break. To power
two circuits which are independent when off.
(5) 5 blade twin make & break. Similar to (1),
but with two blades at 87 feed.
 
 
 
 
 
   

'Yes' under bracket means that the bracket is a fixed part of relay case.
'Loose' means the bracket is supplied loose and can be fitted if required.

  Latching relay.
This relay has a mechanical latch. When the coil is momentarily energised
the contacts operate and 'latch' in that position. To unlatch the contacts
the coil is momentarily energised again.
These relays do not fit into sockets. Mounting is by an integral spring clip.
Coil should only be energised momentarily not continuously. 12V 25A.
