The M-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.
With a mirror polished die cast housing the M-TS-CB Tongue Interlock is suitable for SIP and CIP cleaning processes with high pressure hosing with detergents at high temperatures.
Also available is the M-TSR-CB – see catalogue page.
