Yellow 12x12x7.3mm Tactile 4 Pin Push Button Switch is fully compatible to Omron B3F-4055 Switch. It has 4 pins, 2 pins of each side are connected to each other. So, pressing the switch, connects all 4 pins. It has current capacity of 100 mA. The top of the switch is such that, cap can be easily fitted onto it. Also, the cap has locking mechanism on top of switch, so, it will not get removed easily.

Yellow 12x12x7.3mm Tactile Push Button Switch is widely used as a standard input “buttons” on electronic projects. These work best when you mount it 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 tactile switch 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, testing/instrumentation, and computer/peripherals.
