Color: Black Terminals: 2-pin Material: Copper, Plastic Style: On/Off Self-Locking Rated Current: 1.5A Rated Voltage: 250V Packing List: 10 x Push Button Switches Overall Size: 18 x 12 x 10 mm (L*W*H) The mini size and small tip make it flexible for flashlights during assembly. The contact tip is made of copper, which is conductive when the flashlight is operating in the circuit. The switch shell is made of plastic, which is easy to press and there is no need to worry about leakage. I purchased a set of 10, but I am selling the ones I didn't use.
