Hi everyone, new here, need some help on a circuit design that keeps stumping me.

this is the details

must push a button, relay coil engages and coil stays closed turing on the light bulb

when push button is released, light bulb stays on (holding circuit)

when another button is pushed, relay drops the circuit turing off the light bulb

any assistance i appreciate it greatly !

 

Standard on/off/retaining contact circuit.
