ACV Switch 2p green 54766016

The ACV Switch 2p green 54766016 is a two-pole connector switch designed for manual isolation or selector functions in boiler and burner systems. It features a green actuator and includes an indicator lamp that provides a bright, stable status light for ACV boilers. This switch is heat-resistant and fully compatible with control boards. It fits ACV HeatMaster 71, ACV HeatMaster 71 Delta Pro S 60 Smart E Plus, ACV Delta Pro S 60, and ACV Smart E Plus models.

Parts of this type are selected by number of poles, contact rating (current and voltage must match the controlled load), degree of protection (e.g., IP rating for the panel environment), and actuation style (toggle, rocker, or push-button). When replacing a switch of this class, verify that the pole configuration interrupts all intended phases or lines, and check that the contact material supports the load type (resistive or inductive). Ensure the mounting hole and terminal arrangement match the existing panel cut-out and wiring.

Poor contact in a switch of this kind can mimic control board faults or cause intermittent operation. Inspect for signs of arcing or discolouration on the contacts, which indicate wear or damage. If the equipment fails to switch reliably or shows erratic behavior, check the switch's mechanical operation and electrical continuity.
