Simple project: Swap the on-off switch on a coffee-maker with a relay.
The relay is rated to be safe for wall power. The coffee-pot can take it, obviously. But the old crimp-on connectors that the coffee-pot used to connect to its on-off switch are far to big for the relay.
Ideally, I'd want to attach these wires to the relay directly, without introducing any new components, or adding any gaps between the already-nicely-insulated wires and the relay. Wouldn't want to create any opportunity for mains power to short!
How would you adapt these connectors to fit tight together?
