It consists of a rotary power switch (RPS) 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 SRU indicates when 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. The solenoid is rated for 100% duty cycle. Power to the solenoid can be removed after the trapped key is removed. Removing the trapped key causes the isolating power switch to change state; the normally open contacts open and the normally closed contacts (if applicable) will close.
