Long DescriptionOur Trapped Key Solenoid Release Unit electrically isolates machinery to improve access safety. The unit consists of a rotary power switch and a solenoid. The trapped key can be removed once an external signal is given to its internal solenoid locking mechanism. An indicator light on the solenoid release unit shows when the trapped key can be removed—that is, when power is applied to the solenoid. The solenoid signal only needs to be present when key removal is necessary.Based upon the premise that no one key can be in two places at once, key interlock systems can be configured to provide that a predetermined sequence of events takes place or that hazards have been reduced before operators can become exposed to them.Rotary Trapped Key Interlock Switches are used for electrical isolation of machinery to improve safe access and also as teach boxes in robot cells. Once the power has been turned off, the key can be withdrawn and used in the next sequence of operation such as unlocking an access hatch or allowing valves to be operated.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 can be mounted in a panel or purchased in an enclosure.
