Developed for harsh-duty mobile applications, the J4414 is a cost-effective derivative of one of our mil-grade plunger switches. We’ve utilized the same highly-reliable J4 contact mechanism to ensure long life and outstanding immunity to shock and vibration. This new unitized actuator design incorporates a fine adjust capability, where pretravel can be very closely controlled.
