One aspect of the present invention provides a low-profile switch having the reduced number of components and the decreased assembly man-hours. The switch includes: a base (10), in which a flat circular recess (11) is formed on an upper surface and a central fixed contact (15, 16, 16b, 17, 17b) is disposed in an inner surface of the flat circular recess (11); a spring body (20) that includes a bellows shape in which a reference form unit (23) is repetitively formed, the spring body (20) being annularly disposed in the flat circular recess (11) of the base (10); and an operating body (30) that includes a turning unit (31) fitted turnably in the flat circular recess (11) of the base (10), and an operating projection (34) being provided in an inward surface of the turning unit (31). When the operating body (30) is turned, the operating projection (34) presses an end portion (21, 22) of the spring body (20) to compress the spring body (20), which allows a contact to be switched.

In a device for controlling an operation of an anti-collision switch, the anti-collision switch is provided in a support close to a guide frame that is provided at at least one of both lateral sides of a table frame, to prevent collision of the table frame that is supported on the table support to be capable of moving in a lengthwise direction. The device includes a first lever coupled to the table support so that at least a portion of the first lever moves in a vertical direction according to deformation of the guide frame, and a second lever pressing the anti-collision switch in a normal state and, when a vertical movement of the first lever deviates from a preset height, being moved up by the first lever to remove pressing of the anti-collision switch and operate the anti-collision switch.

L'actionneur mécanique pour manoeuvrer un commutateur électrique à trois positions de commutation comprend un premier organe coopérant avec un mécanisme de transformation de mouvement pour commuter le commutateur d'une position dite « service» dans une position dite « sectionné » ou inversement, et un second organe coopérant avec ledit mécanisme de transformation de mouvement pour commuter le commutateur de la position dite « sectionné » dans une position dite « terre » ou inversement. Dans cet actionneur, le mécanisme de transformation de mouvement comprend un tambour (T) pouvant tourner sur un axe (1), ledit tambour (T) ayant un premier trou radial (T1) et un second trou radial (T2) qui sont espacés suivant ledit axe (1) et sont angulairement décalés l'un par rapport à l'autre, et ledit premier et/ou second organe de manoeuvre est un outil de manoeuvre apte à être inséré dans un trou du tambour. Un tel agencement donne lieu à un actionneur mécanique ayant un nombre de pièces mécaniques réduit, ce qui permet d'en optimiser tant la fiabilité que le coût de fabrication.
