The Murphy 12 Hour Time Switch with Case 12T can automatically start or stop engines or electrical motors after a predetermined time. This time switch can be wired for a open or closed circuit when time expires. It requires no electrical current to operate and have an SPDT contact arrangement. Switch features a precision movement that gives years of reliable service. A built-in stop prevents overwinding. The 12T time switch is enclosed in a NEMA 4 weatherproof enclosure. A hinged, gasketed cover and 1/2 NPT conduit connection allow for a dusttight installation. The enclosure includes a clasp and eye for padlock to prevent unauthorized operation. Instructions for popular engine applications are secured inside of the lid.
