ABSTRACT:
Systems and methods are provided for securing a pin within a raised display system. A washer surrounds the pin. A washer recess comprises a contact surface configured as to bring the washer into a tilted position relative to the pin, such that the washer is brought into physical communication with the pin. A reset mechanism moves at least a portion of the washer to force the washer into a position substantially level relative to the pin, such that the pin can move freely through the washer. An electromagnet holds the washer in the substantially level position when the electromagnet is activated.
