Honeywell 4074EKV Auxiliary Switch Els PW 17895 a compromised trap leads toThe Honeywell 4074EKV is a heavy duty auxiliary switch kit designed for field installation on M6415, M7215, M7415, and M8415 series damper actuators. This 24Vac SPDT snap acting switch allows technicians to synchronize auxiliary equipment, such as fans or indicators, directly with the actuator's shaft position. As a direct equivalent to the 4074EKV U, it features an adjustable cam that provides precise control over the make break points across the
