Definitions

  • the present invention relates to electric switches, in particular to push button switches, for example for electrical installations.
  • switch is a manually operated electromechanical device with one or more sets of electrical contacts, which are connected to external circuits.
  • Each set of contacts can be in one of two states, “open” or “closed”.
  • “Closed” means the contacts are touching and electricity can flow between them, and "open” means the contacts are separated and the switch is nonconducting.
  • a switch can be monostable or bistable. Monostable switches will assume a first state as long as the switch is not operated, and the other state only while the switch is operated. Bistable switches will remain in any of the states and will assume the respective other state only when operated accordingly.
  • pole and “throw” may be used to describe switch contact variations.
  • the number of “poles” is the number of electrically separate switches which are controlled by a single physical actuator.
  • a "2-pole” switch has two separate, parallel sets of contacts that open and close in unison via the same mechanism.
  • the number of “throws” is the number of separate wiring path choices other than "open” that the switch can adopt for each pole.
  • a single-throw switch has one pair of contacts that can either be closed or open.
  • a double-throw switch has a contact that can be connected to either of two other contacts, a triple-throw has a contact which can be connected to one of three other contacts, etc.
  • a rotary switch operates with a twisting motion of the operating handle with at least two positions.
  • One or more positions of the switch may be momentary, e.g., biased with a spring, requiring the operator to hold the switch in the position.
  • Other positions may have a detent to hold the position when released.
  • a rotary switch may have multiple levels or “decks” in order to allow it to control multiple circuits.
  • One form of rotary switch consists of a spindle or "rotor” that has a contact arm or "spoke” which projects from its surface like a cam. It has an array of terminals, arranged in a circle around the rotor, each of which serves as a contact for the "spoke” through which any one of a number of different electrical circuits can be connected to the rotor.
  • the switch may be layered to allow the use of multiple poles, each layer being equivalent to one pole.
  • a switch has a detent mechanism, so it "clicks" from one active position to another rather than stalls in an intermediate position.
  • a rotary switch provides greater pole and throw capabilities than simpler switches do.
  • Other types use a cam mechanism to operate multiple independent sets of contacts.
  • a toggle switch, tumbler switch, or rocker switch is a class of electrical switches that are manually actuated by a mechanical lever, handle, or rocking mechanism.
  • Toggle switches are available in many different styles and sizes and are used in numerous applications. Many are designed to provide the simultaneous actuation of multiple sets of electrical contacts, or the control of large amounts of electric current or mains voltages.
  • the word “toggle” is a reference to a kind of mechanism or joint consisting of two arms, which are almost in line with each other, connected with an elbow-like pivot.
  • the phrase “toggle switch” is applied to a switch with a short handle and a positive snap-action, whether it actually contains a toggle mechanism or not.
  • a switch where a definitive click is heard is often referred to as a "positive on-off switch”.
  • a very common use of this type of switch is to switch lights or other electrical equipment on or off. Multiple toggle switches may be mechanically interlocked to prevent forbidden combinations.
  • a slider switch is a switch that is operated in a linear motion parallel to a surface in which the switch is mounted.
  • Slider switches may have one or more poles, and typically establish or break contact between two adjacent contacts, though establishing contact between multiple adjacent contacts is also possible.
  • a push-button switch has a mechanism that is likewise operated in a linear motion, but the motion is essentially perpendicular to the surface in which the switch is mounted.
  • Push button switches may use a mechanism to convert the linear motion into a toggle motion of a contact member.
  • the mechanism may be designed such that the push button is monostable or bistable.
  • Push-button switches may have multiple poles, and may be single throw, double throw or even triple throw, depending on the mechanism.
  • Push-button switches are typically designed for specific purposes, e.g., either monostable or bistable, as the required mechanisms for each of the purposes may differ significantly.
  • a push-button switch in accordance with a first embodiment of the present invention comprises a base housing, at least two electric terminals for connecting electric wiring, and a movable contact that is in permanent electric contact with a first one of the at least two electric terminals and that can selectively be brought into electric contact with a respective second one of the at least two electric terminals.
  • the push-button switch further comprises an under rocker that is rotatable between a first and a second position around a first axis and that has a protrusion which acts on the movable contact, for selectively bringing the movable contact in electrical contact with a respective second one of the at least two electric terminals.
  • the first axis may be fixedly supported within the base housing.
  • the movable contact may be movable between a first and a second position, e.g., in a translatory or pivoting, seesaw-like motion.
  • the under rocker has a first and a second engagement surface that are disposed at a distance at opposing sides of the first axis.
  • the push-button switch yet further comprises an actuator that is pivotable between opposite sides around a second axis, the second axis being translatable towards the first axis.
  • the second axis may be arranged essentially parallel to the first axis.
  • the actuator has a first and a second prong extending from the actuator at an end opposite of the second axis, each prong of the actuator having a respective engagement surface, for selectively engaging with an associated one of the first and second engagement surfaces of the under rocker.
  • the push-button switch yet further has a button that is arranged in the base housing and movable between an idle position and an operated position.
  • the button has a first surface for receiving a force that moves the button towards the first axis.
  • a second surface of the button located generally opposite of the first surface, is arranged to transfer, directly or via an intermediate element, the force received at the first surface and the movement of the button to the actuator.
  • the second surface may be configured to provide the second, pivoting axis for the actuator.
  • the push button switch is characterised in that the first axis is located between and at least partially embraced by the first and second prong of the actuator when the button is in the second, operated position.
  • the push-button switch is further characterised by a resilient member that maintains the actuator in a non-pivoted position when the button is in the first, idle position.
  • an engagement surface of one of the prongs of the actuator engages with an associated engagement surface of the under rocker and will cause the under rocker to rotate.
  • the actuator while engaged with the under rocker, will be pivoted as the under rocker rotates.
  • the engagement surface of the other prong that is not engaged, due to the pivoting of the actuator, will be moved away from the associated engagement surface of the under rocker and, thus, will not interfere with the rotation of the under rocker.
  • the under rocker and the movable contact cooperate in such a way that the under rocker will remain in the first or the second position when no force is applied, keeping the movable contact in electrical contact with the respective electric terminal, if present. Due to the under rocker remaining rotated in the first or the second position when no force is applied, one of the engagement surfaces of the under rocker remains elevated over the other engagement surface when no force is applied. In addition, the projected distance between the elevated engagement surface and the first axis is smaller than the actual distance. This allows for the engagement surface of one of the prongs of the actuator, while still in a non- pivoted position, to engage with the associated engagement surfaces of the under rocker before the engagement surface of the respective other prong does. After each full operation of the push-button switch the under rocker is in a respective opposite position than before.
  • the comparatively long travel of the button is not blocked by the actuator coming into contact with the first axis, and yet the closest distance between the button and the first axis can be reduced, for obtaining a compact push-button switch.
  • the resilient member comprises two resilient arms, one extending to each side of the actuator, away from the second axis, each arm applying a force directed towards the second surface when the actuator is pivoted to the side of the respective arm, the force targeting to return the actuator into the non-pivoted position.
  • the arm may rest against the second surface, against an intermediate element disposed between the second surface and the actuator, or a respective structure arranged thereon.
  • an intermediate element is arranged between the second surface and the actuator, the intermediate element being arranged to pivotably receive or support the actuator.
  • the resilient member comprises one or more resilient arms extending from the second surface or from the intermediate element in a direction essentially perpendicular to and away from the second surface. At least one of the one or more resilient arms is resiliently deflected by the actuator when the actuator is pivoted. The at least one arm may engage with a corresponding structure, surface or coupling element of the actuator to be deflected and exert a force opposing the deflection when the actuator is pivoted. If an intermediate element is provided, the one or more resilient arms extending from the second surface may pass through corresponding openings in the intermediate element.
  • the under rocker has a support for receiving a resilient element that forces the under rocker into one of the first or second position when no force is applied to the button.
  • the resilient element may, for example, include a helical spring or a leaf spring supported against the base housing.
  • the intermediate element is made from a translucent or opaque material of a first colour, and wherein the button has at least one opening through which a part of the gem is visible.
  • the button may have a different colour.
  • the intermediate element may have a protruding structure that at least partly fills the opening in the button.
  • the base housing is arranged to receive a light source for illuminating the button and/or the intermediate element.
  • the light source may be received in a corresponding mount of the base housing.
  • the mount for the light source is preferably accessible from the outer side of the base housing.
  • the button or the intermediate element may be translucent and may guide light coupled into the button or the intermediate element at one point to other parts of the button or the intermediate element.
  • the protrusion of the under rocker that acts on the movable contact is spring-loaded and movable in a direction perpendicular to the first axis.
  • This embodiment may support maintaining the under rocker in the first or the second position when no force is applied, as any rotation of the under rocker needs to also overcome the spring-loading of the protrusion.
  • a resilient means that applies a force on the button or the intermediate element for returning the button to the first, idle position when no force is applied.
  • the resilient means may comprise a spring, helical or otherwise, or a structure made from a flexible, compressible material that provides spring loading.
  • the facing inner surfaces of the prongs of the actuator are shaped to come into contact with the first axis when the button is depressed by a predetermined distance, wherein, when the button is depressed further, the shape of the inner surface of that prong that is not in contact with the corresponding engagement surface of the under rocker forces the engagement surface of the other prong of the actuator to slidingly separate from the corresponding engagement surface of the under rocker, with which it was in contact.
  • This embodiment may prevent the prongs of the actuator from being deformed or otherwise damaged when the force exerted on the button is too high.
  • the button may be provided with a stop that rests against a corresponding part of the base housing when the button is depressed beyond the point at which the engagement surface of the prong of the actuator has been disengaged from the engagement surface of the under rocker.

Abstract

Un commutateur à bouton-poussoir comprend au moins deux bornes pour la connexion d'un câblage. Un contact mobile établit sélectivement un contact entre les bornes. Un culbuteur inférieur, pouvant tourner entre deux positions autour d'un premier axe, et présentant des surfaces de mise en prise disposées à une certaine distance sur des côtés opposés de celui-ci, agit sur le contact mobile. Un actionneur pivotant, mobile en translation en direction du premier axe, présente deux pointes s'étendant au niveau d'une extrémité opposée au point de pivotement. Chaque pointe vient sélectivement en prise avec une surface associée parmi les surfaces de mise en prise du culbuteur inférieur. L'enfoncement d'un bouton, agencé de façon mobile dans le boîtier de base entre une position de repos et une position actionnée, le déplace en direction du premier axe et transfère le mouvement du bouton sur l'actionneur. Le premier axe est situé entre les pointes lorsque le bouton est dans la position actionnée. L'actionneur est maintenu dans une position non pivotée lorsque le bouton est dans la position de repos.
