MICRO RELAY & STANDARD RELAY - WHAT'S THE DIFFERENCE?

A micro relay is a smaller version of the more popular standard relay and are used when space is at a premium.  

Note, a standard relay is also sometimes referred to as a 'Mini Relay'. 

 Micro relays are more compact than the standard size and are an ideal choice when you need to save space - for example in an ATM fuse box set up with mini fuses.  

They have a smaller rectangular shape compared to the square cubed shape of the standard relay.  

Micro automotive relays use a different terminal number identification system compared to standard mini relays.  

See the list below for micro relay terminal numbering:

1: (4.8mm) Coil

2: (4.8mm) Coil

3: (6.3mm) Common Connection to Terminals

4: (4.8mm) Normally Closed (NC)

5: (6.3mm) Normally Open (NO)
