  • FIG. 11(b) illustrates a rear perspective view of the switch base case (14), according to embodiments as disclosed herein.
  • the switch base case (14) includes the terminal holders (44).
  • FIG. 12 illustrates a perspective view of the switch top case (13), according to embodiments as disclosed herein.
  • the switch top case (13) includes release lever holders (46) that guide the at least one release lever (12) during a release operation of the stripped wire (21), wherein the release lever holders (46) are hinged between the switch base case (14) and the common terminal (19).
  • FIGS. 13(a) illustrates a section view of the switch base case (14) with a hanged release lever (47), according to embodiments as disclosed herein.
  • the switch base case (14) includes casing (48, 49).
  • FIG. 13(b) illustrates a section view of the switch base case (14) with a floating release lever (50) with a floating release lever holder (51), according to embodiments as disclosed herein.
  • FIGS. 14(a)-14(e) illustrates working principal of the proposed electrical device (2), according to embodiments as disclosed herein.
  • An electrical device (2) is provided as illustrated in the FIG. 14(a) .
  • the stripped wire (21) is inserted in the switch base case (14) through the wire entry slots (16) as shows in the FIG. 14(b) .
  • the FIG. 14(c) illustrates the electrical device (2) with the stripped wire inserted condition.
  • An interference (53) between the stripped wire (21) and the terminal spring (18) is provided based on the upward push (52).
  • the FIG. 14(d) illustrates pushing of the external tool (22) in the external tool slot (15) to actuate the release lever (12).
  • the release lever (12) is actuated by the external tool (22) and the release lever (12) is compress the terminal spring (18) and thus the interference (53) is removed between the stripped wire (21) and the terminal spring (18).
  • the FIG. 14(e) illustrates the stripped wire (21) is easily removed from the switch base case (14). Original positions (55) of the release lever (12), the terminal spring (18) are retained after the stripped wire (21) is released. The stripped wire (21) has reduced or bulged diameter with squeezed mark (54) by the terminal spring (18).
  • the sharp edge of the terminal spring (18) retracts to reach its original position and creates the pressure to crush the stripped wires (21) between the terminal spring (18) and screwless terminal cage (17).
  • the installer or end user cannot remove the wire for the screwless terminal since it is strongly held between the terminal spring (18) and the terminal cage (17).
  • To remove the stripped wires (21) without damage to the stripped wires (21) and the release levers (12) are operated by the external tool (22). Further, installer/end user is to use prescribed size of the external tool (22) such as screwdriver and insert into the external tool slot (15) in the switch base case (14) of the switch or socket. Properly guided screwdriver head touches head of the release lever (12) and pushes the release lever (12) further because of the force applied by the installer/end user.
  • FIG. 15 illustrates a cross sectional view of the electrical device (2) in which position of external tool slot is changed, accordingly to embodiments as disclosed herein.
  • the external tool slot (15) is provided after the wire entry slots (16). The other functionality remains same as described above.
  • the proposed the electrical device (2) is advantages to protect the release levers by the switch/socket casing that ensure the long life of the release levers.
  • the release levers are not damaged during and post installation of the switch/socket.
  • Multiple variety of options can be implemented in the product and solution in this safe and secured assembly and operation of the release lever as described above. Insertion and removal of the wires in the different current applications are easy and secured.
  • unexpected disconnection of the wire from the system is eliminated.
  • the continuous current supply to systems is maintained with more safe and secured way.
  • the proposed the electrical device (2) reduces the installation time and installation cost and less no of parts to create rigid screwless installation system.
