# Custom logic output

The Custom logic output part is a standard logic output with a customisable button to monitor the logic signal.

Key points:

- This part is a latching output. It remains on as long as the input signal is 1. The button appears in its down state when the input signal is 1 and the output is on; it appears in its up state when the input signal is 0 and the output is off.
- Pressing the button does not alter the logic signal.
