12x12x7.3mm Tactile 4 Pin Push Button Switch is fully compatible with the B3F-4055 Switch. It has 4 pins, 2 pins on each side are connected. So, pressing the switch connects all 4 pins. It has a current capacity of 100 mA. 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, it will not get removed easily.

12x12x7.3mm Tactile Push Button Switch is widely used as a standard input “button” on electronic projects. These work best when you mount them on PCB but can also be used on a solderless breadboard for temporary connections in prototypes. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed and complete the circuit.

This Push Button also offers reliable dome contact technology and strong tactile feedback, with multiple operating forces to choose from. Applications include telecommunications, consumer electronics, audio/visual, medical devices, button testing/instrumentation, and computer/peripherals.
