Push Button 4 Pin

Push Button 4 Pin is a small and cheap single pole single through switch (SPST) that can be soldered on a PCB. Push Button 4 Usually used as a reset button, this push-button closes a circuit when you press on it. It is rated at 50mA. By default, it is not breadboarded friendly but its legs are flexible enough to be twisted to fit on a breadboard.

This switch has four connections A, B, C, and D. A and D are connected together and B and C are also connected together. When the switch is pushed, all connections (A, B, C, D) are connected together. You can use a multimeter in continuity mode to see what pins are connected together.
