Abstract
An electrical timer having scales for setting switching times and time-of-day. A window exposes only a portion of one of the scales thereby helping a user to set the time-of-day of the timer. In one aspect, the window is located in a cover that hides all but a portion of the time-of-day scale. According to a further aspect, the switching-times scale and the time-of-day scale are located on a dial rotatably mounted on a timer housing that includes a suitable electrical plug, an electrical receptacle, and an electrical switch operable with the scales.
Claims22
An improved timer control interface for an electrical timer used to turn on and off an electrical supply and wherein the interface is used to set desired switching times of the electrical timer and wherein the interface comprises
- a first timing scale and
- a second timing scale, and
- wherein the improvement comprises:
- a surface covering a portion of said second scale, said surface having a window to permit observation of a portion of said second scale, whereby said switching times are set by utilization of one of said scales and time-of-day is set by utilization of the other of said scales.
An improved electrical timer wherein said electrical timer is of a type including
- a first time scale portion marked with indicia for setting timer switching times and
- a second time scale portion located adjacent said first time scale portion, said second time scale portion marked with indicia for setting time-of-day, and wherein said improvement comprises:
- a window located over one of said first and said second time scale portions and through which a portion of said one of said first and said second time scale portions is exposed.
An electrical timer of the type used to automatically turn on and off a supply of electricity by setting of desired switching times on an interface thereof, said electrical timer comprising:
- a housing;
- a dial rotatably mounted in said housing;
- a first timing scale located on said dial;
- a second timing scale located on said dial;
- and
- a cover located adjacent said dial and covering at least a portion of said dial including at least a portion of said second timing scale;
- wherein said cover has a window through which a portion of said second timing scale is viewable.
