A 50 millisecond minimum switch closure is required. IMPORTANT: a dry circuit switch is recommemded. A dry circuit switch is one rated to reliably switch currents of less than 50mA. Use of a switch rated for other than dry circuit may result in failure of the time delay relay to function properly. ** Note: input polarity for DC operation.
