An electrical device can include a cradle having a plurality of integral cradle support regions. A trough is formed through each cradle support region. Each cradle support region includes an aperture that is configured to receive an actuator assembly. Each actuator assembly is movable to open and close electrical connections in the electrical device when the cradle is installed in the electrical device.

A safety switch has a housing, a conducting assembly, a switching assembly and a resilient member. The housing has an on-end and an off-end. The conducting assembly is mounted in the housing and has two conductors and a bimetal strip. The conductors respectively correspond to the on and off-ends and are attached respectively to two separated ends of a circuit. The bimetal strip selectively connects the conductors. The switching assembly has a rocker and a connecting arm. The rocker is mounted pivotally on a top of the housing. The connecting arm connects the rocker and a contacting end of the bimetal strip. The resilient member is mounted between the on-end of the housing and the rocker to stably position the rocker when the circuit is on or off.

The present invention discloses a wall switch with a current control safety module, includes a bottom seat, a triple-conductors assembly, a press-button assembly, a top cover, and a current control safety module. The current control safety module is structurally independent of other parts of the switch and operates via a fuse with a pre-set safety current threshold. The current control safety module makes an open circuit via a blown fuse when the current goes beyond the pre-set threshold.

This invention discloses a rocker switch which provides a reliable movement and a heat-resistant rocker switch by redesigning the position holding mechanism. The rocker switch of the invention comprises: a common contact point, a close circuit contact point, a movable contact point permanently coupled to the common contact point, a rocking switch connecting to the movable contact point and rocking between a close circuit position and an open circuit position, and a position holding mechanism having a spring and an extension rod coupled to one end of the spring. The extension rod is used to change the position of the force acting between the spring and the rocking button and the force acting on the spring in order to improve the life of the spring and increase heat resistance.

THE INVENTION CONCERNS DICTATING AND TRANSCRIBING APPARATUS USING A MAGNETIC BELT RECORD MEDIA AND HAVING A VARIETY OF AUTOMATIC AND SEMIAUTOMATIC FEATURES. THE DICTATING UNIT HAS AN ASSOCIATED MICROPHONE WITH CONTROL BUTTONS FOR ESTABLISHING MODES OF OPERATION, INITIATING FORWARD AND BACKSPACING MOVEMENTS, CONTROLLING THE MARKING OF AN INDEX SLIP, AND SIMILAR OPERATIONS. THE TRANSCRIBING UNIT HAS AN ASSOCIATED HEAD SET AND FOOT CONTROL AND VARIOUS OPERATING CONTROLS, PROVIDED ON THE FRONT OF THE TRANSCRIBING UNIT. TRANSCRIBING OPERATIONS ARE UNDER CONTROL OF A FOOT PEDAL AND INCLUDER STARTING AND STOPPING OF THE BELT MOVEMENT, A SYMMETRICAL FORWARD AND REVERSE REVIEW WHICH IS REPEATABLE, AND OTHER OPERATIONS REQUIRED FOR TRANSCRIBING. EACH UNIT IS PROVIDED WITH INDEPENDENT MECHANISMS FOR RESTORING THE SOUND TRANSDUCER WHEN A BELT IS UNLOADED, CONTROL MEANS FOR ESTABLISHING ONE INITIAL MARGIN DURING RECORDING AND ANOTHER INITIAL MARGIN DURING PLAYBACK, AND MEANS FOR RAPIDLY ALIGNING THE SOUND HEAD IN RELATION TO THE RECORD MEDIA FOLLOWING A MANUAL SCAN OPERATION. APPROPRIATE WARNING SIGNALS TO INDICATE END OF BELT, BELT POSITIONING, ETC. ARE PROVIDED.

An electrical switch responds to acoustic inputs. A microphone integrated into the electrical switch generates electrical signals in response to the acoustic inputs. A network interface integrated into the electrical switch provides addressable communication with controllers, computers, and other networked devices. The electrical switch may thus be installed or retrofitted into the electrical wiring of all homes and businesses. Users may thus speak voice commands, which are received by the electrical switch and sent for voice control of appliances and other automation tasks.

A device for operating multiple functions includes an operating element and a base. The base has side bearings with guide slots, hinge joints with pivot pins, and an actuator. The operating element is mounted in the guide slots to pivotably be mounted to the side bearings about an axis of rotation to thereby be movable between positions. At least one of the positions is assigned to a switching function. The operating element is mounted to the base on a centered bearing between the side bearings. The operating element is supported on the pivot pins. Upon the operating element being actuated to trigger a switching function, the actuator produces a haptic feedback by generating an actuating force on the operating element which causes the pivot pins to pivot in a direction parallel to the axis of rotation thereby causing the operating element to axially displace along this same direction.
