Going to be some project methinks.Bassman,,,, it's an AC relay!!
What a plank(me) just read his post again yes it does say 230vac,still some work involved wiring for switching via push button and relay when there is a mod ready to use.
You can also use a archetrive switch push to make similar to a door bell biased switching better than a push button.
Some containment for all the add ons
