1. A force-based touch sensor assembly comprising a frame, a screen having inner and outer surfaces, a seal for inhibiting passage between the frame and the screen, and a force activated transducer positioned adjacent the screen for detecting forces pushing through the screen due to a touch input, the seal comprising:

  • a flexible membrane having first and second surfaces and first and second sides, the first side capable of being mounted to the frame, and the second side capable of being mounted to the screen;

    whereby the membrane is configured and arranged so that mounting the membrane to the frame and screen creates the seal without passing extraneous forces to the transducers, wherein the first and second sides of the membrane are brought together so as to form a cylindrical shaped seal, and the cylindrically shaped seal is capable of being secured to the frame and the outer surface of the screen to form the seal.
