A safety switch actuation device for keeping the pushbutton switch activated and deactivated remotely, the actuation device comprising a plunger which can be brought by external probing from a standby position, in which it does not switch the pushbutton switch, to an active position, in which it keeps said pushbutton switch actuated, characterized in that the actuation device has a remotely controllable linear drive, a return spring and a return actuator and is designed in such a way that the plunger can be coupled to the return actuator by the remotely controllable linear drive, which is preferably driven by a Bowden cable, under tension of the return spring, which, after deactivation of the linear drive, is pressed by the return spring into a position more remote from the pushbutton switch, thereby entraining the plunger into its standby position.

A window covering in accordance with the invention includes a gearbox assembly comprising a controller incorporated into the gearbox, a motor incorporated into the gearbox, and an external sensor is provided to provide external inputs to the controller in the gearbox assembly. The external sensor may include a security sensor, a temperature sensor, a light sensor, an audio sensor, a smoke detector, a carbon monoxide detector, or a humidity sensor. The controller is further configured to relay sensor information to a remote HVAC system or security system.

Provided are an emergency stop apparatus including a switch unit installed in a work space, electrically connected to a facility, and operable by pulling and a wire which is disposed in the work space so that tension is applied and of which at least one side is detachably mounted on the switch unit and an emergency stop method for quickly stopping the facility at a desired position within the work space in a manner of pulling or pushing the wire.

The invention is a motorized gearbox assembly. The motorized gearbox assembly includes a motor that drives an output shaft. The output shaft actuates a window covering by applying torque to a tilt rod of the window covering. The output shaft extends substantially an entire length of the motorized gearbox assembly. It also has a through-channel that extends substantially an entire length of the output shaft, so that the tilt rod can pass entirely through the motorized gearbox assembly. Because of this, the motorized gearbox assembly can be used for retrofitting blinds. In some embodiments, the motorized gearbox assembly has a diametrically polarized magnet driven by the output shaft, and a position encoder that measures the output shaft's position and number of rotations.

A motorized window covering switching mechanism is described herein. The switching mechanism includes a deflectable arm and a pull cord. The deflectable arm is connected to a first contact, and the pull cord is connected to the deflectable arm such that, as the pull cord is tugged, the deflectable arm deflects to move the first contact toward a second contact, thereby converting gestures of the pull cord into electrical signals that control a motorized window covering. In some embodiments, cord gestures that deflect the deflectable arm include pull sequences, numbers of pulls, strength of pulls, or combinations thereof. Additionally, in some embodiments, a controller receives the cord gestures and translates the cord gestures into operational commands to control and operate a window covering gearbox assembly.
