Embodiment Construction

[0019] The switch has a housing 10 made of electrically insulating resin, which in a well-known manner constitutes the housing of the rail head bolt, as shown in the lower part of the figure, with a notch locking mechanism 12 for use in to lock the fuse block and distribution box shown in the figure or similar. The terminal posts 14 and 16 on opposite sides of the housing 10 are used as terminals for fixed connection with an external cable not shown in the figure, and an electrical connection is established or interrupted between the two through a switch.

[0020] The switch handle 18 can rotate around a shaft 20 installed in the housing 10, and acts on a movable connecting bridge 26 through a conversion cam 22 and a linkage element 24, and the connecting bridge 26 can be in the rib on the housing 10 Bootstrap slide. The terminal post 14 is electrically connected to a connection plate 28 , and the connection plate 28 forms an electrical connection point 30 opposite to the mov...

Abstract

The invention relates to a switch, comprising a housing (10), a switch lever (18), mounted in the housing, which can be pivoted between an on-position and an off-position and a detachable fuse unit, which may be mounted in the housing. The invention is further characterised by a lock mechanism (58, 60), which senses the position of the fuse unit (40) and impedes the movement of the switch lever into the on-position when the fuse unit is not in the correct position.

Description

technical field [0001] The invention relates to a switch, which comprises a shell, a switch handle installed in the shell, which can rotate between the on position and the off position; a detachable safety device installed in the shell, the device has a Install the bracket of the original safety plug-in, the bracket can be loaded into the housing in a turning motion, and can be hooked on the rib of the housing through a braking protrusion; there is also a locking device, which judges the safety device. position; when the safety device is not in the correct position, the switch handle is prevented from turning to the ON position. Background technique [0002] The fuse unit of such a switch, for example constituted by a fuse, is used to break the circuit closed by the switch when the current rises above a permissible value. In known switches of this type, the fuse unit consists of a plug-in fuse, provided with electrodes at opposite ends thereof, ...
