Hello guys,
I'm new here and, while I have a fascination with electronics, I do struggle a LOT.

I have a wireless CNC tool height setter gizmo and would like to repurpose it. As it came, it has a battery operated plunger sensor/switch/transmitter that is NO. When a tool comes down and contacts the sensor pad, it closes the switch and sends a signal to the receiver unit. The receiver unit is NO and closes when a signal is received. I want to use the transmitter with a NC touchprobe. My CNC controller wants a NC signal. So, both the transmitter and receiver need some sort of circuitry to convert the NO to NC. Can someone help me figure out how to do this? The TX circuitry must be as compact as possible, the RX circuitry doesn't matter so much.
Thanks in advance and I hope I have provided enough information to explain.
Scot
