Digital controllers based on MOSFET transistors

In our store, in the digital switches section, you will get switches built with MOSFET technology. It is a technology for manufacturing field effect transistors with isolated gate and integrated circuit circuits. Today, the primary technology used in the manufacture of most integrated circuits is a component of CMOS technology. We have a wide selection of high quality switches and buttons at convenient prices.

What is CMOS technology?

CMOS (Complementary Metal-Oxide Semiconductor) is a technology for manufacturing integrated circuits, mostly digital, consisting of MOS transistors with opposite conductive modes and connected in such a way that when they are in a fixed logic state, current conducts one of them while the other does not. This causes the circuit to statically draw no power, and current from the power source flows only at the time of switching. Then, for a brief moment, both transistors conduct current simultaneously.
