A sensor assembly is provided for a fingerboard latch assembly that comprises: a latch bracket; bolts for mounting the latch bracket to a fingerboard; a latch; and a bracket pin rotatably supporting the latch on the latch bracket to allow rotation of the latch between an open position and a closed position. The sensor assembly has a mounting arrangement that mounts to the bolts, holding a closed-position proximity sensor probe facing downwardly for sensing proximity of a crank portion of the latch and/or the piston head in the closed position, and also holding an open-position proximity sensor probe facing forwardly for sensing proximity of an arm of the latch in the open position.

A switch adapter can include a base having one or more openings, a support coupled to the base, and one or more retainers for coupling a switch to the adapter. The support can have one or more openings between its interior and exterior. The retainer can be adapted to couple to at least one of the base, the support, and a combination thereof. The switch adapter can include one or more switches, such as a replacement switch, and can be adapted for replacing a limit switch with a proximity switch. A proximity switch can be coupled to a switch adapter in one or more positions, and a switch adapter can be adapted to couple with a plurality of different switch mounts. A switch adapter can include a mass compensator for adjusting its center of gravity.

A sensor assembly as part of a wireless alarm system for building entrances like windows and doors. An elongated sensor assembly for detecting a change of state comprising at least one sensor switch configured to detect a given state and a change of state between the given state and at least one other state, a microprocessor configured to detect the change of state of the at least one sensor switch, an antenna system, a wireless transmitter configured to receive a signal from the microprocessor identifying a change of the state of the at least one sensor switch and transmit the signal by means of the antenna system, and a power source for providing electric power, wherein the at least one sensor switch, the microprocessor, the antenna system, the wireless transmitter, and the power source are incorporated in the elongated sensor assembly having a maximum height of less than 5 mm.

A float switch assembly for detecting fluid levels in a reservoir such as in a Christmas tree stand. When the fluid level drops below a predetermined point, the float switch activates an external circuit which provides a visual and/or audible signal. After the fluid level in the reservoir has been restored to the full position, the switch deactivates the external circuit and the visual and/or audible signal turns off. Also disclosed is a Christmas tree stand in combination with the float switch assembly.

The present invention discloses a luminous knob switch and a grill; a knob is rotated to make a relative rotation between a magnet and a magnetic force sensor to control an output signal of the magnetic force sensor to change and thus control operation of a functional member; the luminous knob switch further includes a power adapter to supply power to a functional assembly, and the grill with a luminous knob is powered by the adapter, which eliminates the need to consider battery life and avoids frequent battery replacement by customers.

A button deck includes a substrate and a two-part non-penetrating pushbutton assembly with an upper portion positioned on an upper surface of the substrate and a lower portion positioned on a lower surface of the substrate. The upper portion includes a button face positioned in a button frame that is coupled to the upper surface of the substrate. The button face is configured to be pressed to move within the button frame toward the upper surface of the substrate. The upper portion and the lower portion are configured to work together to provide a signal to an EGM that the button face has been pressed. The pushbutton assembly is non-penetrating because it does not provide any penetration points through the substrate of the button deck.

An enclosure for a video camera and light, the enclosure including a housing; an internal body secured within the housing; one or more connections extending from the housing; an end plate secured to the housing, a first window extending through the end plate; and a second window extending through the end plate; an end cap secured to a second end of the housing and to seal the internal body within the housing; a video recorder positioned within the internal body and positioned such that a field of view extends out of the first window; a light positioned within the internal body, the light being independent of the video recorder and positioned such that a beam of light extends out of the second window and parallel with the field of view; a magnet holder extending from the housing; and a magnet within the magnet holder and engaged magnetically with a switch associated with the light; dislodging the magnet from the magnet holder causes the switch to activate the light.

The pushbutton assembly is non-penetrating because it does not provide any penetration points through the substrate of the button deck.

Disclosed embodiments relate to an auxiliary relay of an electronic contactor. In some embodiments, an auxiliary relay has its conducting state controlled by a plurality of lead switches, in a non-exposed state of contact parts to the outside. This may prevent dust or foreign materials from clinging to the contact parts.

Switch apparatus for enclosures having environmental protection are disclosed. In one example, an apparatus includes a housing having a first cavity and a second cavity, and a mounting plate coupled to the housing. The mounting plate is to cover the first and second cavities. An indicator light is coupled to the mounting plate adjacent the first cavity, and a hand-operated switch coupled to the mounting plate adjacent the second cavity.
