Panel Mount Trapped Key Control Isolation Switch (M-CS)

The M-CS is used for isolating an electrical control circuit. Turning the key to the OFF position opens the safety contacts, allowing the key to be removed and transferred to the next stage in the Trapped Key System. The M-CS-R works in the opposite way to the M-CS, and does not have a key present during normal operation.
