The stainless steel SS-TS Trapped Key Tongue Interlock – Single Key operates on the principle that when the key is “trapped” the actuator can be removed and is in the open position.
When the actuator is re-inserted into the interlock the “trapped” key can then be removed.
Once the released key is in the Isolator Switch or Key Exchange System power can then be re-applied to the guarded area.
Only when the key is inserted and turned in the SS-TS Tongue Interlock can the actuator be removed and the guard opened.
Manufactured in Stainless Steel 316 the SS-TS Tongue Interlock is suitable for SIP and CIP cleaning processes with high pressure hosing with detergents at high temperatures.
