Abstract

PURPOSE: To provide the subject divice wherein non-linear elements are provided in parallel to a plurality of photo-bonding elements connected in series, whereby a current flowing to the switch of an electronic control system is maintained at a constant value to improve the reliability of the device.
CONSTITUTION: The opening and closing state of a limit switch 1 is transmitted to output terminals 8a and 8b through photo-bonding elements 3a and 3b and transistors 7a and 7b. However, since the photo-bonding elements are connected in series to be elongated, the current flowing through the contact does not increase, unlike the case of the elements being connected in parallel, and hence the reliability of the device is improved. By connecting diodes 9a and 9b in parallel to the photo-bonding elements, the opening and closing state of the contact 1 is produced as output at the output terminals 8a and 8b.
