How to avoid the effect of bad operation on steam VR motion Controller Thumbstick?

I am making a teleportation with htc vive controller. And I want to use the thumbstick to trigger the teleportation. But when I press the big round thumbstick button, it sometimes gives me several times of pressing and releasing. The bad effect is that sometimes I will teleport the pawn multiple times with one pressing on the center of thumbstick. And I found that the demo The Lab also has the problem. Can anybody help me, please? Sorry for my English.

If this happens in The Lab for you then it may be a hardware issue. I’ve extensively played The Lab and have not had this issue on three different systems.

Perhaps ask/search Vive’s support?

Here is the community support, not sure if there is another more official support:
