2 Pin SMD Push Button 3x4x2mm Momentary Audio jack These capacitors have a maximumThis 3x4x2mm SMD Tactile Switch is widely used as a standard input Button on PCBs. This switch uses surface mount technology that makes it suitable for limited spaces. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed and complete the circuit. This Push button is also used on NodeMCU, ESP32 board and many other development boards. Specification Product Type Tactile Switch Function Momentary Mounting
