What is it that is supposed to make the "click"? Is it a relay, a pneumatic solenoid valve, an electromechanical actuator or some sort, or what?

How do you have it wired to the controller? Is it powered by a Spike relay, directly connected to a DIO pin, or what?

If you can show us a schematic, or maybe even just a photo of the connection, we might be able to help make the software talk to the hardware the way you want it to.

My last question is not important to the problem you're having, but I'm curious: Why are you using a Select function to turn a boolean into a numeric 0/1, then using that number as the select input of a Case block, instead of just using the boolean to choose the case directly? Are you expecting to add more cases in the future?
