[Noisebridge-discuss] Relay in a pinch?

[Jonathan Foote]

You will probably want a transistor driver for the relay unless you
can find one that latches using 30ma or less. And don't forget the
snubber diode!

I'm fond of solid-state relays which you can drive directly from a
microcontroller, don't generate inductive spikes, and are silent.
