An exemplary apparatus includes a switch, an arm, and a rod. The switch is housed by a housing and includes an actuating tab. The arm is housed by the housing and carries an arm magnet. The arm magnet includes first and second opposed surfaces and an edge surface. The rod carries a float and a rod magnet. The rod is movable between a first rod position and a second rod position at which the rod magnet is in the housing. As the rod moves from the first position to the second position, the edge surface of the arm magnet is configured to move across a facing surface of the rod magnet, thereby moving the arm from a first arm position in which the arm does not actuate the actuating tab to a second arm position in which the arm actuates the actuating tab.

A cooling appliance includes a cabinet, first and second doors connected to the cabinet and a door-opening detection device having a magnetic element disposed on the first door and a magnetic sensitive element disposed on the cabinet. A first magnetic conductive element on the second door can be magnetized by the magnetic element. The magnetic sensitive element can produce a door-opening signal based on a magnetic field of the first magnetic conductive element. The magnetic sensitive element produces the door-opening signal when at least one of the doors is open. In this way it can be detected, by using one suite of door-opening detection devices, if any door among multiple doors is in an open state. The structure is simple, and the number of components can be reduced. Moreover, wires are reduced, which lowers manufacturing costs and difficulty.

A switch system that includes a switch assembly with a housing having a bottom surface that includes a latch pocket defined therein. The latch pocket includes a top surface and the housing defines an interior that includes either a magnetic switch or a magnet disposed therein. One of the magnetic switch or magnet is positioned adjacent the top surface of the latch pocket in the other is associated with the distal end of latch bolt. The system also includes a latch bolt. When the latch bolt is in the unlatched position it is not received in the latch pocket, the magnetic switch is in the first state and an electrical component is in a first state. When the latch bolt is in the latched position it is received in the latch pocket, the magnetic switch is in the second state and the electrical component is switched to a second state.

The fenestration unit monitoring apparatus with tethers are configured to retrofit an existing fenestration unit to incorporate components that are capable of monitoring the locked or unlocked status of the existing lock assembly and/or the panel position status of a movable panel of the fenestration unit. The fenestration unit monitoring apparatus include a lock status sensor located on a tether such that the lock status sensor can be positioned within an existing fenestration unit lock assembly when a monitor housing of the fenestration unit monitoring apparatus is located on the fenestration unit adjacent the fenestration unit lock assembly.

A slidable magnetic switch for controlling the electronic functions of an appliance on the Jewish Sabbath is disclosed herein. A housing with an integrated magnetic slider is permanently attached to the appliance surface directly adjacent to and above its embedded magnetic sensor, whereupon the magnetic force of the extended slider opens the sensor's electrical circuit and disables various auxiliary electronic functions whose operation is prohibited on the Sabbath. The slider is pushed back inside the housing after the Sabbath ends, allowing the sensor's electrical circuit to return to its regularly closed position, enabling the appliance's electronic functions for normal weekday operation. A timer alarm switch mounted within the housing provides an audible reminder to manually activate the magnetic switch each week before the Sabbath begins, or alternatively, to automatically extract the slider from the housing before the Sabbath commences, and retract the slider into the housing after the Sabbath concludes.

A push switch includes a vertically arranged reed switch, a hollow case disposed to surround the reed switch, an annular first magnet fixedly disposed on the lower side in the case to surround the reed switch and magnetized in the axial direction, an annular second magnet disposed to be axially movable on the upper side in the case to surround the reed switch and magnetized in a direction opposite to the first magnet, and a pushing member mounted to the second magnet to move the second magnet to an operating position close to the first magnet at the time of downward operation. The case is positioned so that in a non-operating state, the pushing member is not pressed down within the case. The contact point of the reed switch comes at the center between the first magnet and the second magnet in the axial direction.

The present invention relates to an auxiliary relay for an electromagnetic contactor, the relay including magnet members provided on both sides of a moving member, and first and second conductive members provided on both sides of a frame, whereby an ON or OFF state of the first and second conductive members can be controlled according to the magnet members, in response to a movement of the moving member, so as to configure various contact circuits, such as 1a 1b contact circuit, 2a contact circuit, 2b contact circuit and the like, for the electromagnetic contactor.

The first transmission mechanism of the present invention includes a first permanent magnet, a first rocking member with a rod-like shape that includes one end at which the first permanent magnet is disposed and is extended in Z-axis direction, and two supporting bodies that rockably support the first rocking member at two different positions in Z-axis direction of the first rocking member. The first rocking member is rocked to move the first permanent magnet by an amount of displacement smaller than an amount of displacement inputted to the first supporting body, which is located on a side of the other end of the first rocking member in the two supporting bodies.

Embodiments of the present disclosure include a switching apparatus for a powered adjustment system of a window shading, wherein said switching apparatus includes: a magnetically actuated switch positioned externally to the powered adjustment system and having an on position and an off position, wherein said magnetically actuated switch actuates a drive mechanism of the powered adjustment system in the on position, the drive mechanism being configured to adjust a position of the window shading; and an alignment feature positioned on a housing for the window shading proximal to said magnetically actuated switch, said alignment feature being configured to position a magnet of a switching tool outside the housing to control the powered adjustment system by actuating said magnetically actuated switch between the on position and the off position.

Fenestration unit monitoring apparatus configured to retrofit an existing fenestration unit to incorporate components that are capable of monitoring the locked or unlocked status of the existing lock assembly and/or the panel position status of a movable panel of the fenestration unit. The fenestration unit monitoring apparatus described herein may provide a relatively easy and aesthetically pleasing option to monitor the lock status and/or panel status of an existing fenestration unit with an existing lock assembly already located thereon. The fenestration unit monitoring apparatus may be inserted into an existing lock assembly slot in a frame member of an existing fenestration unit that already contains a lock assembly without requiring removal of the lock assembly from the lock assembly slot.
