Definitions
- the present invention relates to a novel and improved electric switch, and an object of the invention is the provision of a construction which has various advantages or improvements over those of other switches so far in use.
- the switch comprises control means consisting of an operating element constituted by a magnetic bar articulately connected to the control means, the free end of which is susceptible of keeping, by means of magnetic action, in permanent contact with a swinging element able to actuate an operated movable element.
- control means consists of at least one member articulately mounted and disposed inside a window conveniently provided in the body of a front plate, on the back of which is mounted at least one box of dielectric material housing the switch mechanism, said front plate being provided moreover at convenient points with at least two projections protruding over the back of same, projections which are susceptible of being plugged into corresponding sockets or bushings disposed on a support element.
- the operated movable element is constituted by a sheetlike element consisting of at least three tongues, the middle one of which is longer than the side tongues, said tongues being hooked at their free lower end and disposed under certain tension in a hearing conveniently provided in the body of an organ jointly fixed with the intermediate tongue of the operated movable element inside the mechanism housing box.
- This sheetlike element is endowed with a certain degree of flexibility and is self-regulating both in its closed and open positions.
- Figure l is a fragmentary and diagrammatic view of the new and improved switch with the movable operating element in working position.
- Figure 2 is a view identical with that of Figure 1 but with the movable operating element in idle position.
- Figure 3 is a view in perspective of the sheetlike element constituting the operated movable element.
- Figure 4 is a view in perspective of the organ supporting the two shorter side tongues of the sheetlike element.
- Figure 5 is a diagrammatic view of the sheetlike element in working position.
- Figure 6 is a view identical with that of Figure 5 but with the sheetlike element in idle position.
- the new and improved switch comprises an element 1 having the form of a balance element eccentrically swinging on an axle 2 and operatively connected on one side by means of a connecting member 3 to an operated movable element 4, one end of which is connected to one of the terminals 7 whilst the other end of the operated movable element is provided with a contact 5 separable from the counter-contact 6 connected to a second terminal 7 and, on the other side, by means of a magnetized bar 8 one end of which, further away from the balance element, is articulately connected to the operating means 9 constituted by at least one element articulately suspended inside an opening 10 provided in the body of a 2,693,520 Patented Nov.
- the means 9 consist of a plate which is pivoted to the plate 11 and which is located in the window 10 of the plate 11. The plate 9 is maintained in a position flush with the plate 11 by a spring 23; it is swingable clockwise by pressure which may be exerted by a finger of the user.
- the operated movable element 4 can be constituted by a sheetlike element consisting of at least three tongues 16, 17 and 18, the intermediate tongue being longer than the lateral tongues, said tongues being hooked at their free lower end and disposed under certain tension in a seat 19 having the form of a groove conveniently provided in the body of an organ 20 jointly fixed with the intermediate tongue 16 provided with an opening 21 coinciding with the opening 22 in the organ inside the mechanism housing box 12 to the body of the same and connected to the terminal 7.
- the operated movable element constituted by a sheetlike element is endowed with a certain degree of flexibility and is self-regulating both in its closed and in its open position.
- the mounting of the switch is extremely simple insofar as it is only necessary to connect the ends of the cables to the terminals 7 and 7' and plug the protruding portions 13 of the front plate 11 into the sockets 14 of the supporting element fixed to the box embedded in the Wall for the switch to be ready to work.
- the switch of the present invention operates as follows:
- the above-described change of position of the swinging element 1 switches the magnetized bar from its downwardly tilted position to its upwardly tilted position.
- said magnetized bar rotates the swinging element in opposite direction, thus exposing the connecting element 3 to traction, which element pulls the operated movable element causing the same efiect as before but in opposite direction, i. e. the sheetlike element is separated from the counter-contact 6, thus breaking the circuit.
- a device for moving the contact arm to the on and ofl positions comprising a cam-like element, means for pivotally securing the cam-like element forwardly to the contact arm in a plane substantially perpendicular to the plane thereof, a connecting arm pivotally disposed intermediate the camlike element and the contact arm and to one side of the pivotal mounting means of the cam-like element, the cam-like element having a recess formed in the periphery thereof on the side opposite the contact arm, a 25 permanently magnetized rod coacting with the recess, the magnetized rod having a stroke sufficient to move the contact arm through the cam-like element and connecting arm to a point beyond the dead center of the contact arm, and means for applying a force to the free end of the magnetized rod in the direction of the cam like element and alternate on and off movement of" the contact arm.
- An actuator for a switch having an overcenter snap acting element movable to two difierent positions of stable equilibrium, a swinging element mounted for oscillatory movement and connected to said snap acting element, said swinging element having a recess surface with two end portions, a bar element engageable with said recess and mounted so as to have reciprocating and oscillating movement, said bar element and said swinging element forming a magnetic couple in which one of the elements is a permanent magnet so that said bar will be attracted to and follow said recess from one end portion to the other end portion of said recess upon movement of said bar, said bar being biased to one position and movable to a second position, alternate movement of said bar against said bias causing alternate movement of said swinging element and said overcenter snap acting element.
