A boat having an electric motor coupled with an electrical store is disclosed. The electrical store includes a storage element, and positive and negative poles in current-conducting connection with the storage element. An isolating circuit element is operatively connected to a user activatable emergency stop switch. The isolating circuit element is configured to, upon activation of the emergency stop switch, isolate the current-conducting connection between the storage element and at least one of the poles.

In an embodiment of the present disclosure, a condensate level switch mounting assembly includes a condensate level switch having a mounting frame, a first bracket configured to fixedly attach to a condensate drain pan, and a second bracket having a mounting plate configured to engage with the mounting frame of the condensate level switch to secure the condensate level switch to the second bracket. The condensate level switch mounting assembly further includes a fastener assembly configured to couple the second bracket to the first bracket such that an angular position of the second bracket is adjustable relative to the first bracket.

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.

An orifice module for a flow switch system has a cylindrical body which is symmetric about a central axis which defines a metering orifice. An axial central hub holds the stem. The hub connects to the cylindrical body by at least three support spokes which forms a plurality of flow channels angularly disposed about the central axis. The module interacts with the flow switch to enhance the function of the flow switch and also reduces turbulence in the fluid flow system.

A device for monitoring and indicating a fuse tube detachment from a fuse cutout assembly contains a structural body, a tilt switch, a power source, a visual indicator, and an attachment mechanism. The attachment mechanism is used to mount the device onto the fuse tube. The tilt switch monitors the position of the fuse tube. More specifically, when the vertical position of the fuse tube changes to the dropped position the tilt switch is triggered. Thus, the visual indicator is illuminated. The illumination aids in the process of discovering the detached fuse tube. In addition to the visual indicator, the device can also be equipped with a wireless communication device and an alarm system. The wireless communication device can be used to provide the exact location of the detached fuse tube. On the other hand, the alarm system can be used to expedite the process of discovering the detached fuse tube.

A night vision goggle adapter including: a goggle mount assembly; a primary magnet generating a magnetic flux; a magnetic flux conducting unit having a first end and a second end; a first plurality of shunts; and a second plurality of shunts disposed about the goggle mount assembly; wherein the magnetic flux conducting unit may overlap the primary magnet and form a magnetic circuit for conducting the magnetic flux towards the second end of the magnetic flux conducting unit when none of the first plurality of shunts and none of the second plurality of shunts are overlapped by the magnetic flux conducting unit; and wherein the magnetic flux is shorted through one of the first plurality of shunts or the second plurality of shunts when the magnetic flux conducting unit is positioned to overlap one of the first plurality of shunts or one of the second plurality of shunts.

A night vision goggle adapter including: a goggle mount assembly; a primary magnet generating a magnetic flux; a magnetic flux conducting unit having a first end and a second end; a first plurality of shunts; and a second plurality of shunts disposed about the goggle mount assembly; wherein the magnetic flux conducting unit may overlap the primary magnet and form a magnetic circuit for conducting the magnetic flux towards the second end of the magnetic flux conducting unit when none of the first plurality of shunts and none of the second plurality of shunts are overlapped by the magnetic flux conducting unit; and wherein the magnetic flux is shorted through one of the first plurality of shunts or the second plurality of shunts when the magnetic flux conducting unit is positioned to overlap one of the first plurality of shunts or one of the second plurality of shunts.

It is provided a protection device for being provided inside a key fob to selectively inactivate the key fob. The protection device comprises: a first conductive layer; a second conductive layer; an insulator layer between the first conductive layer and the second conductive layer, the insulator layer preventing conductive contact between the first conductive layer and the second conductive layer; and a switch conductively coupled between the first conductive layer and the second conductive layer, the switch being wirelessly controllable to be in a conductive state or a blocking state.
