AC Source SwitchesShip Shore Group

An AC source selector switch is an essential item for any vessel with an on-board AC generator and/or inverter. By isolating power source inputs, the switch eliminates the safety hazard and/or damage that can occur if two AC sources are applied to the same circuit simultaneously.

These switches are fitted with a compact escutcheon plate with engraved switch position nomenclature.

The switches carry cUL approval, are CE marked, and feature heavy duty contacts and a positive step cam mechanism for low resistance contact closure. May be rear mounted in panel with thickness up to 1/4”.
