A disposable handle assembly may include a housing including an end wall at a distal end of the housing and first extension walls extending from the end wall, an end cap attached to a second extension wall on a proximal end of the housing, and a power source positioned within the housing between the distal end and the end cap. The disposable handle assembly may include a pin positioned within the housing, a circuit wire positioned within the housing, and a plate attachment positioned on the end wall between the first extension walls. The circuit wire may be in electrical contact with the contact plate and an end of the power source received by the end cap. The pin and the contact plate may be electrically connected outside of the housing and close an electrical circuit of the disposable handle assembly.
