Definitions
- the invention relates to an electrical switch according to the Preamble of claim 1.
- Such electrical switches are called on / off switches in power tools, such as drills, angle grinders or the like Like., Used. In particular, it can be Trade power tools that operate with direct current become.
- the switch has switch contacts in the manner of a contact bridge attached to a sled are arranged, as well as associated fixed contacts.
- a the slide is a manually operated actuator movable between two positions. In one position namely the off position, the switch contacts are from the Fixed contacts removed and in the other position, namely the on-position, the switch contacts are on the Fixed contacts.
- the sledge and the actuator acts an elastic formed as a torsion spring Means together so that the sled with a kind of Snap movement switchable between the two positions is.
- the invention has for its object the switch to develop further that its lifespan is increased, and that in particular the contact bounce of the switch is reduced.
- the elastic means of the switch according to the invention is as first spring designed in the manner of a pressure point spring. At Movement of the slide affects the first spring with a Switching point backdrop in the sense of generating a pressure point together. This counteracts a spring force Direction of movement of the slide up to the switching point, see above that the movement of the sled from the out to the Initially, the on-position creeps under the approximation of the Switching contact to the fixed contact. Is the Switchover point is overcome, so that it is still there remaining distance between the switch contact and the Fixed contact with a snap movement of the slide kilometer. Since the snap movement only when Covering this shorter distance is a Contact bounces largely excluded. Further Embodiments of the invention are the subject of Dependent claims.
- the elastic means as Combination of the first spring and one on the slide train another second spring.
- the second Spring creates another when the carriage moves Spring force, the further spring force up to Switchover point against the direction of movement of the slide and when overcoming the switch point in the direction of movement of the slide acts, so that the second spring thus is supportive in the snap movement of the slide.
- the The sled When switching from the on to the off position, the The sled is immobile at first and the remains Switch contact on the fixed contact until the switchover point is reached.
- the changeover point is overcome then a sudden separation of the switching contact from Fixed contact by the snap movement of the carriage, so that any arcing that may occur will immediately go out. Destruction of the contacts, especially in the DC operation is thus effectively countered.
- the second spring can be designed as a compression spring. At Movement of the slide from one position becomes this Compression spring during pressure point generation until it is reached of the changeover point excited so that a restoring force acts against the direction of movement of the slide. at Relaxation then occurs when the switchover point is overcome the compression spring, a force in the direction of movement of the Sled works.
- Transfer of manual actuation from the actuator on the contact system can be done by means of a slide.
- the slide stands by acting on the second one Spring with both the sled and the Actuator in operative connection.
- the slide is movable arranged in a guide on the slide.
- Two the sledge assigned approaches are on the slide, with the one the approaches work together with the management and to others one approach to one end of the second spring acts.
- the carriage is accommodated in like a rectangular chamber for the second spring located.
- the slide guide closes on both sides to the recording. On these two sides, the Recording openings for guidance, so that the respective am Slider approach to affect the associated end of the second spring can be inserted into the receptacle is.
- a stop can be made when the slide is attached be arranged, this stop with a corresponding stop on the recording, for example with that at the transition between the leadership and the reception located chamber wall, interacts. It is preferred a game of movement between the two corresponding ones Stops are present, such that when the slide is actuated first acts on the second spring and after overcoming the movement play of the sled with the assigned corresponding approaches from one Position is movable towards the other position. This movement game supports the movement process during Switching, especially with regard to the snap movement as well as the sudden contact separation when switching from the on in the off position.
- the first spring is a Leaf spring formed with a resilient leg.
- the Leaf spring is approximately parallel to the plane of movement of the Arranged sled.
- An approximately V-shaped cam is on End of the resilient leg, the V-shaped Cam with an on an inner wall of the housing for the Corresponding approach to the switch Switching point interacts.
- Leaf spring bow-shaped with two resilient legs in the kind of a U's trained.
- a bracket for the leaf spring is arranged on the slide, the bracket on which the Recording opposite end of part of the guide is located.
- Another third spring can be used as Compression spring is designed to be arranged on the slide. On The end of the third spring lies against a slide-proof stop and the other end of the third spring on a housing-fixed Stop on. This creates a restoring force when actuated of the slide effective, this restoring force also serves to reset the actuator, as soon as the manual action on the actuator is finished.
- a type can be used to hold the third spring rectangular chamber on the slide. Then it is advisable that the slide-resistant stop by one Wall of the chamber is formed, while the housing Stop protrudes into the chamber.
- the switch contact itself is also with a compression spring provided so that in the on position the switch contact can be applied to the fixed contact by means of spring pressure.
- a compression spring provided so that in the on position the switch contact can be applied to the fixed contact by means of spring pressure.
- the first spring should expediently be such Have a spring constant that the one exerted at the changeover point Spring force of the first spring is at least as large as the sum of the spring forces that are exerted by the compression springs on all Switch contacts are exercised. This ensures a Immediate contact separation at the switchover point when switching from the on to the off position. It is also useful the approach of the switching point backdrop asymmetrical with flanks different slopes. Here is the steeper flank of the off position and the flatter flank of the On position facing. On the one hand, this ensures that when switching from the off to the on position first the already mentioned creeping contact approach up to The switchover point is reached. On the other hand, too ensures that, in conjunction with the power of Pressure spring on the switch contact a contact separation at Switching from the on to the off position before reaching the Switching point is excluded.
- the switch according to the invention is therefore also suitable for switching large switching capacities.
- the moving parts of the switch have less friction than before. This reduces wear and tear The lifespan of the switch is further increased.
- the switch according to the invention also advantageously has a smaller hysteresis between the on and off position than the previous switch. The user receives thereby a smoother shift feeling.
