A safety lock as taught herein comprises first and second members and is configured to lockably mount to an interlock switch. In one or more embodiments, the second member slidably couples to the first member and slides between a disengaged position that allows for mounting and an engaged position that engages a corresponding switch actuator opening in the interlock switch. In at least one embodiment, the second member projects through an opening in the first member into engagement. The first and second members may include corresponding lock openings, allowing the second member to be locked into the engaged position. In at least one embodiment, the first member conforms at least partially to the exterior of the interlock switch, e.g., it spans at least one exterior corner of the interlock switch. The first member may include an engagement finger to engage a corresponding switch actuator opening of the interlock switch.

A pressure-sensitive mat system includes a mat with a recessed mat connector and a cable assembly that includes a cable connector that detachably mates to the mat connector. The cable connector is sized to the inset area of the mat connector and thus conforms to the dimensional envelope of the mat. Conforming to the mat's dimensional envelope minimizes tripping hazards, reduces the likelihood of cable damage, and permits the use of flush fitting edge trim strips that may be used to secure the mat to the floor. In one embodiment, the cable connector mounts to the mat connector via threaded fasteners. The use of threaded fasteners permits compressive connector engagement, which enhances inter-connector electrical contact integrity and permits the use of an interposed connector gasket that provides watertight sealing when the two connectors are compressively engaged. The connector(s) may include other features such as air vents to vent the mat interior.
