12x12x15mm Tactile Push Button SwitchTactile push button switch is Normally Open switch. The tactile button connects the circuit for the time it is kept pressed and as soon as it is released the circuit is disconnected. The Tactile Push button has 4 pins. Two pins are connected internally. These Tactile push buttons features a through hole design. Its high precision mechanism offers acute operation and long life. It is majorly used as standard input buttons in electronics circuits.
