This Tactile Push Button Switch is widely used as a standard input “button” on electronic projects. These tactile Push Buttons work best when you mount them on PCB but you can also use them on a solderless breadboard for temporary connections while prototyping. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed and complete the circuit. The top of the switch is such that, the cap can be easily fitted onto it. Also, the cap has a locking mechanism on top of the switch, so, you do not have to worry about it easily coming out or falling off the switch.
