A 50 millisecond minimum switch closure is required. IMPORTANT: A dry circuit switch is recommended. 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.
