Abstract: A switching device including a plurality of electrical switches, and an activation lever adapted to substantially simultaneously change the switches from a first state to a second state in response to a single physical input.

Abstract: A gage having a motion detection mechanism magnetically attached to a pressure sensing diaphragm. The motion detection mechanism is magnetically coupled to a pointer rotation mechanism configured to indicate the position of the diaphragm and the corresponding pressure sensed by the diaphragm.

Abstract: A cover retention mechanism for releasably locking a cover to a base such as a gage housing. The cover retention mechanism includes a base lock having a receiver and a receptacle, and a cover lock having a latch attached to an end of a flexible arm. The latch is selectively movable between a retracted position wherein the latch engages the receptacle to prevent rotational movement of the cover with respect to the housing from the closed position toward an open position, and an extended position wherein the latch is removed from the receptacle and the cover is rotatable with respect to the housing from the closed position toward the open position.

Abstract: A battery pack system may include a battery pack and a battery pack holder. The battery pack holder receives the battery pack and couples a battery pack terminal to a load associated with the battery pack holder. The battery pack includes an operation handle external to a battery pack housing. The operation handle is coupled to an operation member via an operation shaft that passes through the housing. A safety circuit of the battery pack couples power supplied by a battery to battery pack terminals based upon position of the operation handle. An operation member of the battery pack extends a locking member into an opening of the battery pack holder when the operation handle is in the engaged position, and retracts the locking member from the opening when the operation handle is in the disengaged position.

Abstract: An enclosure for a gage including a housing and cover. The cover includes one or more mounting lugs and the housing includes one or more mounting mechanisms. Each mounting mechanism includes an inclined ramp to facilitate removal of the cover from the housing by rotational movement of the cover with respect to the housing.

Abstract: A gauge for indicating a measured variable such as pressure. The gauge includes a motion detection device including a drive magnet that is adapted to be moveable in response to changes in the variable. The pointer rotation device includes a pivot member, a power magnet coupled to the pivot member, and one or more director members located adjacent the power magnet. Each director member includes a generally helical flange. A pointer is coupled to the pointer rotation device. The director members and the power magnet form a magnetic field adapted to magnetically couple the pointer rotation device to the drive magnet. The pointer rotation device is adapted to rotate about a rotational axis. Movement of the drive magnet in response to changes in the variable rotates the pointer rotation device and the pointer about the rotational axis such that the pointer indicates the measured variable.
