Filed:

Apr 20, 2000

Appl. No.:

09/552837

Inventors:

Thomas P. Karnowka - Littleton CO
David A. Easter - Arvada CO
Timothy N. Teen - Belleville NJ
Douglas K. Milby - Arvada CO
Armand Rozenberg - Rehovoth, IL

Assignee:

Easter-Owen Electric Company - Arvada CO

International Classification:

H01H 3500

US Classification:

307119, 307118

Abstract:

An electrical switch and a method of generating an electrical switch output signal. An electric switch senses both pressure placed upon the switchs surface and the contact of the object exerting the pressure on the switch. When both conditions exist, the switch is activated. The electrical switch may employ a piezoelectric element to recognize the application of pressure, a capacitive sensing circuit to recognize the presence of an object applying the pressure, and a microcontroller circuit to control output switch circuity upon satisfaction of both conditions precedent. The electrical switch can be configured to provide a continuous output signal for the duration that the switch is pressed after the conditions are satisfied or to switch between open and closed states each time the switch is pressed after the conditions are satisfied.

Abstract:

A cover for a sewer basin with a pump is provided with upper and lower members. The bowl-like lower member has a central cavity which may be closed in a water-tight fashion by placement of the upper member onto the lower member in a frictional fit. A flanged surface on the lower member allows it to be sealed in water-tight relationship over a maintenance entry into the basin. A control panel for the pump is mounted in the central cavity. Access may be had to the control panel without a need to open the basin, and access may be had to the basin interior without a need for opening the central cavity or the control panel housed therein.
