Application No. 09/833,978
Osika discloses a portable electrical circuit control unit. The portable electrical
circuit control unit including an electrical receptacle or outlet for receiving the plug on a
conductor from a motor and also including an extension cord for connection to a source
of electricity. The portable electrical circuit control unit further includes a switch means
including a bridging contact means in continuous electrical connection with the
receptacle or outlet and selectively operable to electrically connect with the extension
cord and complete a circuit to the receptacle or outlet.
Osika teaches that the circuit through the switch in "On" position to the outlet in
the unit is made through a plug 24 (shown in Figure 1) connected into a live outlet, and
the extension cord 26 comprising three wires 27, 28 and 29, the first two connected to
stationary contacts 31 and 32 (shown in Figures 2 and 2a), and the third wire 29
connected to a ground terminal 33 (shown in Figure 2). The switch includes bridging
contact members 48 (shown in their two positions in Figures 2 and 5) with one end
portion 52 of each in physical and electrical engagement with the respective two
stationary contacts 53 and 54 which in turn are either integral with or in electrical
connection respectively with U-shaped receptacle tabs or contacts 56 and 57 (see
Figures 2 and 8) for the electrical outlet in the unit. As shown in Figures 1, 2 and 8,
insertion blades 81 and 82 of a plug 79 are inserted into the stationary receptacle
contacts 56 and 57 in the outlet and ground contact 78 of plug 79 is inserted into the
