One challenge that will need to be addressed when developing this project into a product will be that finding appropriate pushbuttons.

Requirement for Push Button

• The push button needs to be able to small enough to fit inside small tubing that has a diameter of less than 0.25 inches. This is so that it can be portable and easily bendable.
• It needs to be normally-closed SPST switch of which there are few options available. It must be this type in order for the resistor to get shorted which is how the project works.
• It must have an acceptable life of at least 100k cycles for a durable consumer product.
