Single tongue Interlock with control isolation - single key with 3NC 1NO contact block (actuator/key not included*)

The TS-CB single key tongue Interlock with contact block operates on the principle that when the key is "trapped" the actuator can be removed and is in the open position. When the key is in the "trapped" position the contacts switch to the auxiliary position in the contact block. When the actuator is re-inserted and the "trapped" key removed the safety contacts in the contact block are then re-made.

Once the released key is in the isolator switch or key exchange system power can then be re-applied to the guarded area. Manufactured in stainless steel makes it suitable for SIP and CIP cleaning processes with high pressure hosing with detergents at high temperatures.

Watch our video below to see how the key exchange system works . . .
