Abstract
An electric control device having a high power thick film controlled circuit including a photon activated switch all on an insulating substrate. A photon emitting control element in a low power control circuit is supported from strips extending from the lead frame of the device. The strips are bendable, allowing the emitting element to be folded over the photon activated switch to thereby establish optical coupling and electrical isolation between the control and the controlled circuits.
