What is a D Latch Flip Flop Circuit for a Control Relay?

[codyrodgers]

I need help! I'm really close to figuring out this Control Relay circuit but I'm running out of time.

Circuit Description: Plug in the circuit and the light turns on. Press the momentary button and the
light goes off. Press the momentary button again, and the light turns back on after one second.
Press the button again and the light goes back off. Repeat...

I've been reading on the D latch and Flip Flop logic a bunch, but I can't figure out how to apply it to
using relays! I know I'm missing something little can somebody help me PLEASE! If somebody could
draw a quick ladder diagram and upload a picture it would save lives. My co-workers and I are
stuck and out of time.

Doesn't a relay just fire a contactor? (takes a normally open switch and closes it). If the relay gets a signal of "1" from the flip flop, it shoud close the contactor and turn on light.

When relay gets a "0" from flip flop it should open contactor and turn light off.

As far as the "quick" ladder diagram...that's up to you!
