2916XG2I.04 New Ruwido (Now Apparently Bourns) 1-Pole Push Switches with 4MM Short Pushbutton Lever, for Board Mount Through Hole Solder Electronics, Part Number 1543-650 (or possibly 1543-600).  Each bid quantity is for a Lot of Twenty (20) Switches.  You may bid / buy any number of lots, up to the total quantity available above. These were purchased at an electronics liquidation last year, and they were brand new in the original factory boxes.  We packaged them in heavy Ziplok bags for resale.  The boxes indicate that these are "potentiometers" (Picture #6, 7 & 8) but the knobs do not turn, and they remained a mystery for a while.  Upon further researching the part number, we located a datasheet that identifies them as a pushbutton switch.  We are guessing that Ruwido just had a bunch of leftover potentiometer boxes and hated to waste them.  When the button is pressed, they make a tiny "click" that can be felt but not heard.  The button only travels a fraction of a millimeter. According to the calipers: Housing dimensions:  .385" x .385" x .287" (9.97 mm x 9.79 mm x 7.30 mm) Button length:  .157" / 4 mm Button diameter:  .157" / 3.99 mm Solder pin length:  .180" / 4.58 mm Solder pin width:  .040" / 1.01 mm Solder pin spacing / pitch:  .197" / 5.00 mm According to the manufacturer: 1543 Push Switch Characteristics Switch Travel:  0.6 to 0.8 mm Actuating Force:  0.8 to 2.4 N Bounce Time:  45 ?sec. max.
