push button
The V16F-11Z-Y part is a product from Onpow, a Chinese manufacturer of industrial switches and buttons. It is a 16mm, momentary push button with a metal shell and an illuminated LED. It is rated IP65, meaning it is waterproof and dust-proof, and it can operate between -25°C to 55°C. The contact configuration is normally open, meaning that when the button is not being pressed, the contacts are open. This makes the V16F-11Z-Y well-suited to applications such as control systems, vending machines, and kiosks.
