I need a relay that has two outputs on 12V: output A and B. It can be in three states: A, B or none. I must be able to switch between A and B from an Arduino, for example via a simple protocol (PWM?), or just first pulse is A, next pulse is B, etc... I have googled around for something like that but…

Does a relay with switchable output exist?

Two relays. Two digital pins.
