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. These switches feature a precision movement that gives years of reliable service. A built-in stop prevents overwinding.
The 24T (24 hour) time switch is enclosed in a NEMA 4 weather- proof enclosure. A hinged, gasketed cover and 1/2 NPT conduit connection allow for a dust-tight installation. The enclosure includes a clasp and eye for padlock to prevent unauthorized operation.
Instructions for popular engine appli-cations are secured inside of the lid. 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.
