Trapped Key Interlocks - Tapeswitch Corp


Trapped Key Interlocks For Power Isolation and Access Control Machine Guarding

Tapeswitch Corporation offer a complete line of power isolation and access control machine guarding trapped key interlocks to many global industrial and commercial markets.

The AIE is a double key, stainless steel, access interlock suitable for machine guarding on hinged and sliding doors, gates and fences. The KS - powersafe electrical switch is a key driven electrical switch suitable for the isolation or switching of low (20,32, 63 or 150A) current. The key exchange units, such as X, Y, Z  are for multiple access point machine guarding.

 Key interlocks are a machine guarding solution for the control of hazardous energy, eliminating the need for a procedural lockout tag out system and are approved for such use in the US under the ANSI standard Z244.1 - Control of Hazardous Energy (Lockout/Tagout and Alternative Methods). The trapped key interlock product line is extensive, providing solutions for both power interlocking and control circuit interlocking, machinery with different power sources, even pneumatic and hydraulic, machinery with fixed or variable run-down times, harsh environments, provided full body access, meaning a person can’t be locked in access areas if gate is shut because the machine’s key is needed to start the interlocking process, and robot compounds, where access must be restricted to the end of a cycle products. The product line is well engineered and offers the competitive advantage of integrating unique key code configurations, heavy weight mechanical components, durable stainless steel keys and other safety guard accessories, such as key caps for extra protection from particulates, which can deter the mechanisms of the lock in normal conditions in most trapped key product lines.
