WebJan 23, 2024 · A pinch point is where two objects come together and a body part, most commonly the fingers and hands, can get caught. While pinch point hazards most often involve the fingers and hands, they can also affect other parts of the body. What are examples of pinch points? WebWhen the voltage applied to the drain is increased beyond VSAT, the pinch-off point moves further towards the source, reducing the effective channel length, Leff, as shown in Figure …
