24VAC DPDT (Double Pole Double Throw) General Purpose Relay suitable for most ducted vacuum systems. This relay has dual contacts, one set of contact in each row. For single motor unit, only one row is needed. Leaves the the other row unconnected, it can then be used as a spare/replacement when the first contact is worn. Use both contacts if the power unit has twin motors. For ducted vacuum, always use "NO" (Normally Open) contact.
Note: You can use this relay to replace other types of relay as long as the voltage and current requirements are met.
