    摘要: A limit switch having a fixed casing, an actuating part moveably support by the casing, and a pair of contact sets which are adapted to be activated by the movement of the actuating part, one for producing a normal switch output and the other for producing a stroke signal which serves as data for evaluating the appropriateness of the stroke of the actuating part. The other contact set may produce a signal when the actuating part has moved a certain distance more than the minimum stroke for activating the first contact set. Thus, the output from the second contact set ensures a certain stroke margin of the actuating part. Further, the second contact set may produce another stroke signal when the actuating part has been displaced close to the maximum permissible stroke of the actuating part so that an excessive stroke of the actuating part may be detected. The contact set may be purely mechanical or may also be a combination of a mechanical switch and a photoelectric switch.

    摘要: A limit switch comprising a case (1) housing a switching unit (2), a head (3) secured to one end of the case, a rotary shaft (4) rotatably supported by the head and having a flat portion (14), a manipulation lever (7) secured at a butt end thereof to the rotary shaft which supports at a tip (7B) end thereof roller (8) means for detecting an object, a return coil spring (16) provided in the head which applies a force through a return plunger (15) to the flat portion of the rotary shaft to return the manipulation lever to a free position, a disk cam (19) secured to the rotary shaft and having a projection (30) formed on a peripheral portion thereof in a position corresponding to the free position of the manipulation lever, manipulation plunger means for the switching unit which is driven in response to rotary movement of disk cam and elastic stopper means (31) disposed in the head for contacting the projection of disk cam and for braking the manipulation lever when manipulation lever is returned to the free position, whereby the lever is prevented from being swung back beyond the free position. Therefore, the switching unit is prevented from chattering.

    摘要: Bei einem Schalter, insbesondere Mikroschalter, mit wenigstens einem Kontaktelement und mit wenigstens einem auf das Kontaktelement wirkenden Betätigungselement, ist vorgesehen, daß das Betätigungselement eine drehbar gelagerte Betätigerwippe ist, welche in zwei Lagezustände bringbar ist, wobei sie in einem Lagezustand das Kontaktelement in einen ersten stabilen Schaltzustand überführt und in dem anderen Lagezustand das Kontaktelement in einen zweiten stabilen Schaltzustand überführt.
    Dieser Schalter weist bei einer vorzugsweise gegebenen Miniaturisierung eine hohe Schaltsicherheit auf, wobei er aus wenigen Bauteilen ausgebildet ist.

    摘要: An electric quick-break switch with forced opening of the contacts comprises a fixed part (10) containing two pairs of fixed contacts (12, 13; 14, 15) and a movable part comprising an operating button (17) where to two quick-release toggle springs (18) are pivoted which retain a movable contact bodge (16), wherein, below the two points where said toggle springs (18) are pivoted, two semicylindrical seats (22) are provided which accomodate in hinged relationship a first end or inside end each of two L-shaped levers (20) resting each in sliding relationship with a first leg of the "L" on a raised portion (21) rigid with the fixed part of the switch, provided with two circular projections (24) at the elbow of the "L" adapted each for sliding against a sidewall of cylindncal seats (23) on said fixed part and with outside ends or dual lugs (25) moving along two symmetrical arcuate paths with respect to said operating button (17). In the event of a malfunction of the movable contact bridge (16), said levers will interfere with the same to force the normally closed contacts open and the normally open contacts of the switch closed.
