摘要:
A device for protecting an electrical installation including an insulating body electrically defining an internal housing, the protective device including, within the internal housing: an active component of a device for protecting an electrical installation; a disconnection system for disconnecting the active component moveable between a contact position corresponding to a connected state of the active component and an open position corresponding to a disconnected state of the active component; a disconnection indicator, where the disconnection indicator is secured in movement to the disconnection system and the disconnection indicator and the insulating body are arranged to have a first configuration, which corresponds to the contact position, and a second configuration, which corresponds to the open position, the relative positioning of the disconnection indicator with respect to the insulating body in the first configuration being visually distinct from the outside of the insulating body from the relative positioning of the disconnection indicator with respect to the insulating body in the second configuration.

A hot water kettle has an on/off switch, which is adapted to automatically switch from a closed position to an opened position when water which is present inside the kettle has been boiling for a while. The on/off switch is operable through a button element (6), a position of which is determined by the position of the switch. Inside a space (61) of the button element (6), a vibratory member (20) comprising a flexible bar (21) is arranged. When the on/off switch is in the closed position, a free end (25) of the bar (21) is retained by an actuator (10). As soon as the on/off switch switches to the opened position, this end (25) of the bar (21) is eventually released, as a result of which the bar (21) starts to vibrate and the button element (6) starts to resonate. In this way, an acoustic signal is generated.
摘要:
An electrical distribution device that includes a terminal for providing a connection to a first conductor, a spring mechanism having a first end that is electrically connected to the terminal, and a second conductor electrically connected to one or more internal components of the device. The spring mechanism has a first condition and a second condition. In the first condition, the second end is electrically connected to the second conductor by solder. When the solder melts, the spring mechanism moves from to the second condition in which the second end is no longer electrically connected to the second conductor, thereby protecting the internal components from the fault condition that lead to the overheating. A condition indicator may also be provided for indicating a fault condition.

A single bimetal automatic changeover thermostat has heating, cooling and changeover switches mounted to the bimetal. A single control point adjustment lever for rotating the bimetal has separate shaped heat and cool set point indicators which are movable along a temperature scale.

Comparison is made between an output from a temperature detecting element for detecting temperature of a control knob of a switch for controlling temperature, with a reference signal generated in association with a preset temperature of the control knob, and at least means for cooling or/and heating the control knob is driven on the basis of result of the comparison, whereby the control knob is held at preset temperature, so that the temperature of the control knob can be held at the preset temperature by a relatively simple control device.
