Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers.

Switches are devices that allow electric current to flow when closed and prevent current flow when opened. Switches, All Types are a high level search form that includes options for all switch types. Search forms for specific switch actuator types are also available

Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions

Disconnect switches rapidly disconnect from power supplies in the event of an emergency

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.

Signal switches activate or deactivate a signal once an event has occurred

Power switches are used to apply power to or remove power from instruments such as large-scale factory equipment

High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life.

Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts.

Protective relays and monitoring relays detect or monitor for abnormal power system conditions.

Relay boards (multiple relay modules) are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply

Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications

Noncontact safety interlock switches couple a moveable guard door with the power source of the hazard. For noncontact actuating interlock switches, the guard door is linked to the control circuit contacts via a magnetic or electronic field

Mechanical safety interlock switches couple a moveable guard door with the power source of the hazard. When the guard door is opened, the power is isolated, ensuring that the machine does not pose a hazard while an operator requires access

Emergency stop switches are devices that users manipulate to initiate the complete shutdown of a machine, system, or process
