Dual Limit Switch

Series 51-1 Dual Limit Switch provides visual indication of valve position, as well as remote electrical indication of “valve open” and “valve closed”. The single pole double throw Micro-Switches can be connected to open or close an electrical circuit when the valve opens or closes. The adjustable collars are normally set to contact the trip arms to indicate “valve open” and “valve closed”. The collars can be positioned on the stem by loosening the set-screws to actuate the switches at the desired point of valve travel.
