The 1571563-2 is an SPST-NO tactile switch designed and manufactured by TE Connectivity. It is a top actuated surface mount switch, meaning it is activated by being pressed from the top. It is a single pole, single throw momentary switch, meaning it has two terminals and will remain in the on or off state until used. When activated, it creates an electrical connection between the two terminals which can be used to control a device or circuit. The switch features top-actuated, surface-mount contact technology with a light-touch and audible click sound for easy identification. The switch is rated up to 50 VDC at 0.05A and comes in a compact, rectangular package measuring 3.6 mm x 3.1 mm x 1.5 mm.
