Murphy Time Switches can automatically start or stop engines or electrical motors after a pre- determined time. These time switches can be wired for a open or closed circuit when time expires. They require no electrical current to operate and have an SPDT contact arrangement. A built-in stop prevents overwinding.
Murphy Time Switches are designed for use in the oil field, irrigation systems or anywhere equipment must operate or be controlled for a predetermined time.
Mounted on a post or in a panel away from vibration and shock, these time switches give accurate, long term service.
