摘要:
The invention relates to a device for switching an electric connection, especially a hinge switch (1) with a pin that can be actuated from outside the device. The device further comprises actuator means that are arranged on said pin and that interact with switching means that switch the electric connection once a switching point is exceeded. The aim of the invention is to provide a device according to the preamble of claim 1 which allows the switching point to be adjusted and readjusted simply and permanently with relatively few constructive elements. To this end, the actuator means are displaced in a radial and/or an axial direction in relation to the pin (3) by means of an adjusting device in such a manner that the switching point can be adjusted to a given angle position of the pin (3).

The invention relates to a device (1) for maintaining a locked and closed state of a space-separating device (2) in a releasable manner, in particular a protective device of a machine (4) having a first part (6) with an opening and a second part (8), said parts being movable relative to one another, the opening therefore being at least partially closable, wherein the device (1) comprises a latch (18) by means of which the closed state of the space-separating device (2) may be locked, a holding element (30) by means of which the latch (18) may be kept in the latched position, and a release element (36) by means of which the catch of the latch (18) may be released, and wherein the catch of the latch (18) may be lifted by a rotational movement of the release element (36) relative to the latch (18).

The invention relates to a locking system for a safety switch, comprising a reading head (2) and an actuator (3), which have a respective first and second module (10, 14) containing electric and/or electronic components, which can be caused to interact electrically in a contactless manner in order to control the safety switch. Said system is characterised in that the actuator (3) can be locked on the reading head (2) by means of a controllable electromagnet (7), which co-operates with a counter-element (12), that the counter-element (12) and/or the electromagnet (7) is/are connected in a fixed manner to a corresponding base element (13), which is fixed to the actuator (3) or reading head (2), but can be pivoted in relation to said base element and that the first and/or second module (10, 14) is/are integrated into the respective counter-element (12).

The invention relates to a device (1) for monitoring the state of a protective device (2), wherein said protective device (2) comprises a first element (4) provided with an opening (5) and a second element (6) which is movable with respect to the first element (4) in such a way that the opening (5) is closable at least partially, the device (1) comprises a locking device provided with a locking element (18) by which the close state of the protective device (2) is removably lockable and is blocked in the currentless state of the locking device, said locking device is activable by the movement of the protective device (2) from the open to the close state thereof. Said invention is characterised in that the device (1) comprises a blocking device (40) provided with a blocking element (41) and said blocking element (41) prevents in the currentless state the activation of the locking device by blocking the blocking the movement of the locking element (18), thereby leading to the closed state of the protective device (2).
