Abstract

Light controlled switching modules are provide. In embodiments, a light controlled switching module includes: a housing; a light controlled semiconductor switch mounted to the housing, the light controlled semiconductor switch including a semiconductor body; at least one light source mounted to the housing in a spaced relationship from the light controlled semiconductor switch and positioned to direct light emitted from the at least one light source toward the semiconductor body; and first and second electrodes mounted to the housing and connected to the light controlled semiconductor switch, wherein the first and second electrodes are configured to have variable resistance between the first and the second electrode.
