Circuit : Abu-Hafss, Pakistan
This circuit takes a non-locking press button switch and uses the ubiquitous 555 timer to converts
the switch action to a toggle switch.
This simple circuit, built with a 555 and a few passive components, will energize and de-energize a relay at the
push of a button. Any type of momentary action push-to-make switch can be used. Pushing the button once will energize
the relay. And pushing it again will de-energize the relay.
