    Abstract: A fuse holder comprising a frame (2), spring means and limiter means (6), the frame (2) comprising a first contact member (8) and a second contact member (10) adapted to receive an end (18) of the fuse between them, the spring means being adapted to press the contact members (8, 10) against the fuse end (18) to achieve an electrically conductive connection between the contact members (8, 10) and the fuse end (18), and the limiter means (6) being adapted to define the largest possible depth of the fuse end (18) in the installation direction between the first (8) and second (10) contact members. The spring means comprise a substantially circular arch-formed ring spring (4) adapted to also serve as the limiter means (6).

    Abstract: The present invention relates to a switch device for controlling electrical equipment. Such a switch device comprises a body piece (15), a sliding member (14) and contact surfaces controlled by the sliding member (14), means for latching the sliding member (14) into a closed/open position of the switch and for unlatching the sliding member (14) from said positions, a spring-arming plate (11) and switch actuator springs (10). The invention is implemented by making a slot (33) into the sliding member (14) that controls the second movable set of contact surfaces in the switch and adapting compatible interlock means (34) to the housing or body piece (15) of the switch, said interlock means serving to inhibit the movement of said sliding member (14) by virtue of partially entering the slot (33) made into the sliding member (14). Additionally, the spring-arming plate (11) is provided with a projection (32) capable of covering the slot (33) made into the sliding member (14) and thus preventing the interlock means (34) from inhibiting the movement of the sliding member (14) when the switch is being opened or closed. The switch device is also provided with another set of springs (31) for storing the mechanical energy required for a remote-controlled operation.
