Clasic sugar cube case relay. Footprint: Relay_SANYOU_SRD_Series_Form_C from
Relays_THT,pretty library. For the schematic symbol: use G5Q-1 from
relays.lib but you have to edit pin numbers to match this footprint.
BTW: Don't know why KiCad footprints for standard power relays have pins numbered as 1, 2, 3, etc. while many of manufactures enumerate relay pins as follows: A1, A2 for coil and 11, 12, 14, 21, 22, 24, etc. for contacts (EN 50005 standard)?
