Abstract:
An electromagnetically operated solid state timing device having switching contacts and features which will permit the device to act as a direct replacement for an electromagnetically operated pneumatic timer. The device includes an electromagnet, a permanent magnet latch, a snap switch, solid state circuitry and accessible controls so the device may be easily programmed to actuate the snap switch an adjustable time delay after the electromagnet is energized or deenergized.
Abstract:
A printed circuit board module including a housing which is formed by two substantially identical molded parts that are secured to each other to provide an enclosure for one or two printed circuit boards. The two molded parts each have femaleand male-type posts extending through openings in the printed circuit boards. The posts are arranged so the male posts on the respective parts telescope into the female posts to position the printed circuit boards within the interior of a housing provided by the two parts. The housing positions one of the printed circuit boards so portions of the board may be plugged into a female receptacle and includes means for guiding the housing relative to the receptacle.
