For a "medium-small" sized relay I'm currently using the Hongfa HFD41A, nom= inal=20 3A (max 5A) SPDT contacts... https://nz.apexelex.com/specs/relays/HFD41_HFD41A.pdf For smaller, quieter, and more expensive option you might try a Solid State= Relay=20 (optocoupler). Some fairly impressive new Toshiba parts at DigiKey... https://www.digikey.co.nz/products/en/relays/14?k=3DTLP35&newproducts=3D1 Problem of course is that, if used directly, they are not as tolerant to br= ief over=20 current events as relay contacts are.
