Product Description

The "keyboard key" circular pot piece is a keyboard arrangement that requires a long lifespan or sealed interface. These bullet switches provide positive feedback through auditory and tactile clicks. The "keyboard" circular shrapnel is made of nickel plated stainless steel and provides a very reliable user interface (over 500000 to 1 million cycles). The "keyboard" dome can be directly placed on the PCB, which will save assembly costs and improve reliability. Bulk or roll form can also be provided for automatic assembly and placement assembly applications. The "keyboard" circular pot top is designed to be placed on the PCB instead of soldered. The pot piece is fixed in place using a "keyboard" adhesive gasket. If there is adhesive at the bottom of the top sealing surface, it helps to keep the dome in the correct position. The switch needs to be ventilated between at least two domes or through a PCB in order to function properly.
