A disconnector having a stack of modular contact boxes surmounted by a snap-action switch box, each modular contact box including a rotary contact and two fixed contacts which are accessible from the outside. The switch box further includes a driven indexing element which is rotatably associated with a spindle loading support and at least one spring connected between the two in order to load them elastically with respect to each other following a mutual rotation about the central axis. The disconnector has a single actuation rod which passes through all the modular contact boxes coaxially to the central axis and is fixed in rotation to all the rotary contacts.

In one embodiment, a method includes, by a switch device, determining a position of an on/off input selector, the on/off input selector being located within a switch device, in response to determining the position of the on/off input selector is in an off position, operating one or more solid state switches to suspend current to one or more load-side terminals, determining whether the one or more load-side terminals of the switch device are electrically isolated, in response to determining the one or more load-side terminals of the switch device are electrically isolated, generating a prompt via a graphical user interface, and receiving, via the graphical user interface, one or more inputs, the one or more inputs including at least a request for safety lockout instructions.

A motor control center includes an enclosure comprising an isolation switch, a main contactor device, and a ground switch device. The isolation switch is selectively manually operable between a connected state and a disconnected state. In the connected state the isolation switch is adapted to conduct electrical power from an associated power source to the main contactor device and wherein the isolation switch in the disconnected state interrupts conduction of electrical power from the associated power source to the main contactor device. The main contactor device is selectively operable between a conductive state and a non-conductive state, wherein the main contactor device is adapted to electrically connect the isolation switch to the ground switch device and to an associated electrical load when the main contactor device is in its conductive state and wherein the main contactor device disconnects said isolation switch from the ground switch device and the associated electrical load when the main contactor device is in its non-conductive state. The ground switch device is manually operable from an open, ungrounded state in which the main contactor device is electrically disconnected from a ground path to a closed, grounded state in which the main contactor device is electrically connected to the ground path. The motor control center further includes a first interlock device operably connected between the isolation switch and the ground switch device, wherein the first interlock device prevents movement of the isolation switch from the disconnected state to the connected state when the ground switch device is in the grounded state.

The present teachings provide for a device with a membrane and an underlying switch, an underlying switch actuator, or both that has a unique tactile pattern that is felt through the membrane when the membrane is aligned with the switch, switch actuator, or both, corresponding to the electrical state of the device. The membrane, the switch, the switch actuator or a combination thereof can be repositioned from a first position to a second position so that a different tactile feel is present through the membrane corresponding to a second electrical state.
