hi
When i create this circuit I get strange results using the logic probe.

The inputs for the Nand are not low whilst the switches are not pressed, the logic returns no reading.
I am using tactile switches. Is this the issue? I dont know much about switches but I can only think that i am using the wrong type.
If i remove switches wire up inputs to ground or supply i get expected readings.
Anyone help please?
Thanks
