The lock includes a normally closed switch configured to open in response to the voltage being applied across the electromagnet. The lock includes a normally open switch configured to close in response to the voltage being applied across the electromagnet. A method of opening a lock includes applying a voltage across an electromagnet in a lock. The electromagnet is configured to open a latch in the lock in response to the voltage being applied across the electromagnet. The method includes causing the electromagnet to open the latch in response to the voltage being applied across the electromagnet. The method includes opening a normally closed switch by applying the voltage across the electromagnet and closing a normally open switch by applying the voltage across the electromagnet.
