Struggling to find a high-current DC contactor with pulse latching (step latch) that switches state with each pulse without requiring polarity reversal.
Existing high-current contactors are either continuous coil (drain power, require polarity reversal) or latching types that need polarity change; no readily available pulse-latching contactor with 500A DC rating and simple SPST control.
