16A Step Relays - 20 Series
The 20 Series are available as DPST-NO or SPST-NO + SPST-NC step relays. On each successive energisation of the relay coil the contacts will change state thus providing a step or "flip flop" sequence of operation. An override test button allows manual advancement of the step sequence and individual mechanical flags provide visual indication of contact status.,Typical applications would include the control of lighting where push on push off or sequential operation is required, automatic opening and closing of doors, gates, etc. Use in portable or battery powered equipment requiring contact status to be maintained without continuous supply to the coil and functions where manual override operation is desirable.
