Limit switchare activated by cams connected to the actuator shaft. When activated, they send discrete electrical signals to indicate actual valve position, usually confirming that a valve fully opened or closed operated remotely. In addition, these signals can be used as interlocks in a control system. For example, locking out a pump until its supply valve has been opened. Mechanical switches should be housed in an enclosure (Switchpak), which will also provide visual position indication. Proximity (magnetically latching switches) are hermetically sealed which makes them less susceptible to moisture intrusion. Select the appropriate switch type and area classification.
