Mechanical Vibration Switch
FWMurphy, was born out of one man's search for simple, reliable engine protection. While Frank W. "Pat" Murphy was a sales manager for a major equipment distributor in the 1930's, he found that his customers' main complaint was "burned up" engines. They were equipped with poor quality, non-indicating safety switches which were difficult to test and often inoperative. Pat decided to develop a simpler yet more effective "Safety Switch". We are an authorized distributor of Murphy Switch.
