  • Switch device with a trouble detecting and indicating function
    Patent number: 4992777
    Abstract: A novel electro-mechanical switch device is disclosed which is suitable for use in a factory production line to detect and control the flow of workpieces or articles of manufacture along the line. The switch device includes a pair of switches (101, 102) operative in response to the workpieces passing thereby along the production line, a switch circuit (13) electrically connected to the switches (101, 102), and a moisture detector (15). The pair of switches are so designed that the operation of one switch is delayed with respect to the other. The switch circuit (13) functions in response to the operation of the switches and the moisture detector (15) to provide a warning signal when one of the switches fails to operate within a predetermined delay time with respect to the other switch, as well as when the moisture detector senses a presence of moisture.
