The future of electrical switching contacts under the influence of electronics

After a short presentation of the principles of switching of electromechanical switches, transistors, MOSFETs, thyristors, triacs, and GTOs (gate turn-offs), the requirements for the different applications of switching devices are elucidated. The replacement of electromechanical switches by electronic ones is considered for energy distribution, energy in industry, control and regulation, for domestic installations, domestic equipment, and railways, electric vehicles, and motorcars. It is concluded that electronic components will not completely replace switching contacts, but that in the future both types of switch will complement each other.<>
