Hello all, I am very new to all the electronics stuff so bare with me. I am building a scuba dive light and I need help with making a piezo switch work. The light is built in two pieces, the light head(torch) and the battery pack(canister). The piezo was chosen due to its extreme durability and waterproofing. The problem i ran into is that the piezo is momentary, and I need to turn it into an on-off switch. How can I accomplish this? Thanks for any help that might be given.
