Abstract

An elevator safety tool (20) and method for safely short circuiting an elevator switch. The elevator safety tool (20) may comprise a control module (5) that receives elevator operating status data and determines whether an elevator operating status is normal or service, and a relay (6) including a switch (12) that is movable from a closed to an open position when the elevator operating status changes from service to normal. The tool (20) may also include a pair of pen heads (3) connected to the relay (6) by short stubs (4). The method may comprise receiving data, determining an elevator operating status based on the data, closing a switch (12) to allow conduction between two pen heads (3) when the elevator operating status is determined to be service, and opening the switch (12) when the elevator operating status is determined to be normal.
