I'll try explain my problem:
I am trying to make a simple circuit that powers on when a momentary switch is pressed but then stays on until the power source (feeding the lamp) is then removed.
I want to be able to turn on the circuit with momentary power through switch1, once the power of switch1 has been stopped (press has finished,) then lamp1 should stay alight until we disconnect the wire where the red circle is marked.
When power is reapplied (the red circled area is reconnected,) lamp1 should be off until switch1 is pressed again.
The scenario: I have a pump that should start when a button is pressed (not a switch with constant power,) the pump should stay running until the power to the relay->pump is removed. Then when it is removed, the pump will obviously stop pumping. Then the relay should reset to off so that when power comes back on the pump should not start until the button is pressed again.
Can the relay can self feed itself as shown below,or is there an easy way to make this work?
