A switching device has a housing-mounted contact and a movable contact. The movable contact is provided for making contact with the housing mounted contact, The switching device has a switch lock with a latch and a latch support, wherein the latch support has a latching location for latching the latch to the latch support, wherein the switching device furthermore has a hand switching lever. A connecting rod is mounted movably on the latch support, the connecting rod bearing against a projection of the hand switching lever when the hand switching lever is arranged in the position in which the contacts are in contact. An actuation of the hand switching lever—for separating the movable contact from the housing-mounted contact—moves the connecting rod and thereby releases the :latching of the latching support to the latch.

The present application is directed to a switching device for LV electric installations. The switching device can include an outer casing and one or more electric poles. Each electric pole can include one or more mobile contacts and one or more fixed contacts adapted to be coupled or uncoupled. A mobile contact assembly is operatively coupled with the mobile contacts such that the mobile contacts move together with the mobile contact assembly, The mobile contact assembly is adapted to reversibly move between a first contact position, in which said movable contacts and the fixed contacts are coupled and a second contact position, in which the movable contacts and the fixed contacts are uncoupled. A mechanical control assembly is provided for operating said mobile contact assembly.

A plurality of control elements extend from the base portion of a control module in a materials handling vehicle. The control elements are located adjacent to one another, wherein at least one of the control elements includes mounting structure that permits the control element to be selectively mounted to the base portion in at least first and second positions. The first position defines a first distance between the control element and an immediately adjacent control element and the second position defines a second distance between the control element and the immediately adjacent control element, the second distance being greater than the first.

A key assembly to be installed on a keyboard is provided. The key assembly includes a base plate including a snap-fit hook, a scissor member including a pivot shaft, and a keycap. The keycap is disposed on the scissor member and connected thereto. The scissor member is disposed on the base plate and connected thereto. A bending portion of the snap-fit hook has a chamfer structure to which the pivot shaft is pivotally connected in such a manner that the vertical gap between the snap-fit hook and the pivot shaft is reduced.

In order to improve a hand-actuated transmitter unit for vehicles, in particular for handlebar-controlled vehicles, comprising a housing, an actuating lever which is movable relative to the housing and is coupled to a transmission element such that an actuation of the actuating lever is transmitted by means of the transmission element to a slave unit, such that further functions of a vehicle can be controlled, it is proposed that a detector unit which detects with at least one detector a transition of the actuating lever from a non-actuated state to an actuated state and vice versa is associated with the transmitter unit.

The present invention implements, through a simple structure, the prevention of an electric shock caused by contacting an output terminal in a conducting state. This electric shock protection structure is provided with: a protective cover (40) which changes an output terminal into a non-conducting state by pressing a power switch (51) during the transition of the output terminal from a covered state to an exposed state; and a housing cover (60) which cannot be moved when the output terminal is in the non-conducting state by having an L-shaped curved section (60A), which is positioned on a different surface from the surface on which the output terminal is disposed, does not contact a contact section (44A) of the protective cover (40) when the protective cover (40) exposes the output terminal, and contacts the contact section (44A) when the protective cover (40) covers the output terminal.

An electric switch, in particular for manually operated electric tools or appliances with an electric motor, is switchable from outside by means of a plunger. A changeover device is provided for setting the direction of rotation of the electric motor, which changeover device can be activated for example by a tappet arranged on the outside. The switch is constructed very compactly, which simplifies the sealing of a switch of this type.
