De Dietrich 95325361 bipolar switch

This is a bipolar switch, catalogue article 336.559.002, carrying the manufacturer codes 95325361 and 336.559.002 under the De Dietrich brand. Although listed under plugs and connectors, the part is a switch that can interrupt both line and neutral conductors in a mains circuit. In boiler and burner systems, a bipolar switch of this type is commonly used as a service disconnect for the burner control, fan, or pump – providing a means to isolate equipment during maintenance or in response to a safety signal. When selecting a replacement bipolar switch, the key parameters are the contact rating (voltage and current capacity), the number of poles (two in this case), and the mounting and terminal arrangement. Such switches may be designed for panel mounting, DIN-rail mounting, or as part of a plug-in connector assembly. Verify that the switch form (e.g., toggle, rocker, or push-button) and the electrical rating match the original part. A mismatch in rating or contact material can cause overheating or premature failure, especially in circuits carrying motor or transformer inrush currents. Because this item appears in the plugs and connectors category, it may integrate a connector housing or have terminals that mate with a specific harness. Ensure the pitch, keying, and conductor cross-section are compatible if it is part of a plug-in system. Poor contact in such components can mimic many electrical faults – from intermittent lockouts to false flame signals – so a careful check of the switch and its connections is recommended during fault finding.
