Macromatic Alternating Relays
The alternating action is facilitated by a control switch, typically a float or pressure switch. As the float or pressure switch opens, the initial load is turned off and the alternating load activated.
Alternating relays are most often used with pumps, compressors, and thermostats.
Macromatic offers several types of alternating relays for controlling different load situations:
Duplex: Two-load control
Triplex: Three-load control
