Allen-Bradley 440T Prosafe Rotary Trapped Key Interlock Switches

The Allen-Bradley 440T Rotary Trapped Key Interlock Switches are designed for electrical isolation of machinery, improving safe access and can also be utilised as teach boxes in robot cells. Once power has been disconnected, the key can be withdrawn and used in the next sequence of operation, such as unlocking an access hatch or allowing valves to be operated. The rotary switch is available as either panel mounted or purchased in an enclosure.
