A non-mechanical-interfacing electronic switch or a mechanical-interfacing electronic switch are controlled to modulate between an active state and an inactive state based on electronic action. The switch includes an aperture defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal to a receiver along a signal path. To control the non-mechanical-interfacing electronic switch, a mechanical lockout device having a protrusion is inserted through the opening of the aperture along the insertion path. To control the mechanical-interfacing electronic switch, a mechanical control part have a protrusion is moveable to interrupt the signal. Methods of locking the non-mechanical-interfacing electronic switch with the mechanical lockout device as well as methods of locking the mechanical control part of the mechanical interfacing electronic switch with the mechanical lockout device are also provided.
