the toggle member 36. When the finger operable member 41 is pivoted clockwise
(Figure 2), the spring 44 will be compressed and will exert a force which will cause the
toggle member to pivot suddenly in a counterclockwise direction, or snap, to the open
position when the member 41 has been pivoted a predetermined distance in the
clockwise direction. Similarly, when the toggle member will be moved clockwise, from
the open position to the closed position when the finger operable member 41 is pivoted
counterclockwise.
Freeman teaches (column 2, line 42, to column 3, line 18) that:
In use, the prongs 17 and 18 of the adapter are inserted into an electrical
outlet and are thereby connected to an electrical circuit. The prongs 15 and 16
of the plug are inserted into the adapter 10 and contact the extensions 33 and
31, respectively, so that the switch may either close or open an electrical circuit
between contact element 10 [sic, 19] and the prong 17. The prongs of the plug
(not shown) of an electrical device 46 are inserted into the apertures or recesses
27 and 28 of the adapter and contact the elements 19 and 20.
It [sic, If] it is now desired to control the operation of the electrical device
by use of the switch 11, the finger operable member 41 is moved clockwise to
cause the toggle member 36 to snap to open position where it does not connect
the extension 33 to extension 30. If the switch 11 is now closed, current will flow
from the prong 17 through the extension 33, conductor 12, switch 11, conductor
13, and the extension 31 to the contact element 10, and from the contact
element 19 the current will flow to the electrical device 46 and from the electrical
device, to the contact element 20 and there through the connecting portion 29 to
the prong 18. If the switch 11 is now opened, the circuit to the electrical device
46 will be broken and it will be rendered inoperative.
When, for one reason or another, it becomes undesirable to control
operation of the electrical device by use of the remote control switch 11, the
finger operable member 41 is moved counterclockwise to move the toggle
