Mains Controlled Flip-Flop Relay, Plug-In 11 Pin

The A-FFR Mains Controlled Flip-Flop Relay alternates between two output states each time mains power is applied for 30 seconds or longer and then removed, commonly used to alternate two pumps for duty and standby operation. It is suitable for electricians and pump installers needing simple mains-controlled pump alternation without external control wiring.

• Application: Duty/standby pump alternation using mains power switching only
• Control method: Apply power for 30+ seconds, then remove, to toggle state
• Memory: No memory — state holds until next power cycle
• Mounting: Plug-in, 11 pin base

Key Features

• Alternates two pumps for duty/standby operation using only mains switching — no separate control wiring needed
• 30 second minimum power-on time avoids accidental toggling from brief outages
• Remains in its new state until power is applied and removed again
• Standard 11 pin plug-in format for easy panel fitment
