the switches do have lamps in them but they are not required, the switches are there to latch the relay on so when power is lost to either relay it unlatches and stops the other supply, like an interlock circuit one is dependant on the other.

The switches i have used are on off two button switches one NO and one NC, the NO switch gives power activating the relay and hence giving power through its contacts to itself and the NC switch is used to break the circuit de-energising the relay.

You could of course use two seperate switches per relay one momentry NOand one momentry NC. Im just lazy and opted for the one with a light in it... (i like lights!!.. before someone else chimes in)..


Rick

if your on a tight budget let me know and ill post over a couple of switches without lights FOC..
