The CPI switch story started over 70 years ago designing waterproof switches for the military back in WWII. That knowledge has evolved in this modern product line which see’s use in a wide variety of applications. Generally speaking, after folks get tired of in-field failures of those cheap offshore made imported switches, they end up at our door.

CPI’s deceptively innocent looking pendant switches actually represent decades of switch research, field testing, and manufacturing advances that allow affordable US based mass production with incredible efficiency. These switches come in dozens of electrical configurations, with specifiable endurance ratings and contact parameters.
