2. Junction box - Wikipedia

   en.wikipedia.org/wiki/Junction_box

   A small metal, plastic or fiberglass junction box may form part of an electrical conduit or thermoplastic-sheathed cable (TPS) wiring system in a building. If designed for surface mounting, it is used mostly in ceilings, concrete or concealed behind an access panel—particularly in domestic or commercial buildings [2].

3. Trapped-key interlocking - Wikipedia

   en.wikipedia.org/wiki/Trapped-key_interlocking

   This is a trapped-key interlock on the door of an electrical switchgear cabinet. It is attached with one-way security screws to discourage casual removal, which would defeat the interlock scheme. Trapped-key interlocking utilizes locks and keys for sequential control of equipment and machinery to ensure safe operation. Trapped-key interlocks ...

4. Interlock (engineering) - Wikipedia

   en.wikipedia.org/wiki/Interlock_(engineering)

   To prevent access to the inside of an electric kiln, a trapped key system may be used to interlock a disconnecting switch and the kiln door. While the switch is turned on, the key is held by the interlock attached to the disconnecting switch. To open the kiln door, the switch is first opened, which releases the key.

5. Electronic lock - Wikipedia

   en.wikipedia.org/wiki/Electronic_lock

   Electric locks may be connected to an access control system, the advantages of which include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded. Electronic locks can also be remotely monitored and ...

6. Electrical connector - Wikipedia

   en.wikipedia.org/wiki/Electrical_connector

   The movable (less fixed) connector is classified as a plug (denoted P), [37] designed to attach to a wire, cable or removable electrical assembly. [38] This convention is currently defined in ASME Y14.44-2008, which supersedes IEEE 200-1975 , which in turn derives from the long-withdrawn MIL-STD-16 (from the 1950s), highlighting the heritage of ...

7. Electric strike - Wikipedia

   en.wikipedia.org/wiki/Electric_strike

   This is exactly the same principle as a child safety door lock which is installed on car doors. Electric strikes on AC allow someone outside the door to hear when the door is open. The buzzing noise is typically made by applying alternating current (AC) to the strike instead of direct current (DC). When using a DC powered strike, the sound is ...
