Abstract: An annular switch (SW) for detecting contact is provided on an operating lever (R6), and when the annular switch detects contact, an operation screen (104) pre-associated with the annular switch (SW) is displayed on a display (104) screen of a display unit (104). Operation mode images representing functions included in an operation subject are displayed on the display screen of the display unit in association with a rotation direction and a sliding direction of the annular switch (SW). A function is selected by rotating and sliding the annular switch, and the selected function is executed when the annular switch (SW) ceases to detect contact.

Abstract: A rotary switch for activating selected functions in a hand held device. One embodiment of the invention provides a rotary switch having a rotatable switch selector. Whenever the switch selector is rotated, it reduces the diameter of a torsion spring causing the torsion spring to contact a switch contact and signal a microprocessor to selectably power a particular circuit or a step in a routine.

Abstract: This is directed to a bend switch constructed from two substantially co-linear elongated bodies having opposing contact surfaces. In an open switch position, the contact surfaces remain apart, preventing electrical coupling. To close the switch, a user can bend the elongated bodies relative to each other to cause the contact surfaces to meet, thus creating an electrical coupling. Each elongated body can have several independent conductive portions. The bend switch can include a movable space member placed between the elongated bodies to maintain the contact surfaces a predetermined distance apart in the open switch position. The movable space member can include preferred or non-preferred bending orientations, equilibrium positions, and/or a potentiometer for closing the switch. The bend switch can control one or more functions (e.g., microphone, volume, or playback controls) of an electronic device (e.g., portable media device or cellular telephone) coupled to the bend switch.

Abstract: An improved electromechanical switch designed to operate at frequencies from DC through microwave has terminal probe tips that are formed from an alloy of noble metal and contoured with a pattern of peaks and valleys in order to provide better contact wiping operation and capture of wear debris. The switch incorporates damper elements to reduce switching contact bounce, thus providing increased contact life as well as higher quality signal switching.

Abstract: An improved electromechanical RF switch provides enhanced reliability and lifespan by incorporating a middle plate between the case and base elements for locating the guide pins, reed holders and reeds to increase accuracy in critical component alignment. The middle plate reduces required precision during assembly of the switch, thus increasing assembly accuracy while reducing labor cost. The guide pins are made of a hard insulator such as glass to generate less wear particles, and the reed holder has a groove filled with lubricant to trap any wear particles that result from sliding friction during switch operation. Optionally, a low-friction bushing is used within the case bore to further reduce sliding friction during reed holder travel. The reeds are made of thin, flexible metal and have ends shaped so that when the ends contact switching terminals, a wiping action removes any surface contamination from both the reed ends and the terminals.

Abstract: An attachment for attaching a main circuit breaker in an electrical panel has a uniquely constructed hold-down for the circuit breaker and a headed screw for fastening the hold-down in the panel. The hold-down is a non-electrically conductive part, such as a plastic. A circuit-breaker-engaging projection for engaging a circuit breaker projects from a first side of the hold-down body and a gripping tab projects from a second side of the body opposite the first side. A shank of the headed screw passes through a through-hole in the hold-down body to thread into a hole in a base pan. The screw is tightened against the hold-down body to hold it, and in turn the main circuit breaker, in place. In such an installed condition, the main circuit breaker cannot be removed easily from the panel unless the screw is intentionally unscrewed by a tool sufficiently to allow movement of the hold-down to a position that enables the main circuit breaker to be removed.

Each conductor path of the switch contains a connector having two positions, one position connecting the conductor path and a second position interrupting the conductor path.

The actuator is shaped and mounted to override the pins, the actuator containing one or more ridges and one or more indentations. When a ridge overrides a pin, the pin is depressed and the conductor path is connected. When an indentation overrides a pin, the pin is released and the conductor path is interrupted.
