I have the following relay. The pins are numbered 1, 2, 3 and 5, rather than the more usual 85, 86, 30 and 87.
I would like the following confirmed:
- 1 = 85
- 2 = 86
- 3 = 30
- 5 = 87
Thanks

I wonder where the datasheet is and the 4th spade pin. Must be a hidden chassis gnd thread underneath – Tony Stewart Sunnyskyguy EE75 Jun 29 '19 at 23:07

1@SunnyskyguyEE75 the 4th pin is just visible - the end just shows clear of the middle one... – Solar Mike Jun 30 '19 at 4:21

There are only 4 pins and no other threads – Mark Tickner Jun 30 '19 at 11:57
The numbering system is given in DIN 72552.
- 1 = 85 (can probably be swapped with 86)
- 2 = 86
Since it's just a normally open contact ...
- 3 = 30 I would call this 87 as it is the 'hinge'/common.
- 5 = 87 I would call this 87b.
