Replacement Transfer Switch for PD52DCS
Updated 09/29/2025 | Published 09/02/2025
Question:
I have a pd52dcs auto transfer relay switch when I plug in shore power it doesn’t work until I tap the unit as if the switch is sticking. Is there anything I can do to repair or does it need to be replaced and if so what would the new part be because I don’t see it on progressives website. Thanks

Hey Bob, the Progressive Dynamics Transfer Switch - Metal Case - 50 Amp - 120V/240V # PD52 (Alternatively PD52V) and the PD52DCS/PD52DCSV are both part of the PD52 series but there are some differences. Both share the same voltage rating and current ratings. The # PD52 is slightly smaller in size and weight, and has a different control board. It also does not include a remote, which the PD52DCS has.
The other differences are additional features the PD52DCS has that the # PD52 does not. It has open neutral, reverse polarity, under voltage and over voltage protection. It also has multimode surge protection. I would recommend the PD52 to replace what you have as it does sound like yours is damaged and in need of replacement.
