Intermatic Four-Function Stepper Relay (143RC140) lightingbulbs A pump like this isThe Intermatic Four Function Stepper Relay is a replacement electrical switching component used in compatible control applications. Stepper relays are designed to advance through switching positions as control signals are received, allowing multiple functions to be managed from a supported control arrangement. This part is commonly used when a system no longer changes functions correctly or when an existing relay has failed. Use this relay only with
