I'm thinking of connecting the contacts of several cheap reed relays (which I already have) in parallel to connect a meter shunt (probably 1A, maybe more), because I think this will be better for this purpose than a single higher rated rated relay. Occasional switching under load is likely, but usually this will be the relays opening or closing at a current around the rating for a single relay.
I'm wondering if, since the turn on/off times for each relay won't be exactly the same, to even out the load a bit I should give each pair of contacts a small snubber network consisting of a capacitor connected across them, and a low value resistor < 1 ohm, in series. Or is it not worth bothering? Or should I just get a bigger relay?
