- Small electrical switches such as Snap switches, microswitches or the like work Manufacturing tolerances of the contact system due to the small Dimensions particularly strong on the switching point of the Contact system. It can therefore with such switches be necessary to adjust the switching point later.
- the invention has for its object a method for adjusting the switching point of an electrical To design the switch so that the switching point of the Contact system can be easily adjusted subsequently can.
- the adjustment process is also intended for one largely automated mass production of the switch be suitable.
- the bearing is for the Contact tongue of the contact system and / or the contact tongue itself and / or the fixed contact of the contact system and / or a Part of the actuator in the direction of movement Adjustable actuator.
- This attitude of the camp and / or the fixed contact and / or the contact tongue and / or part of the actuator preferably takes place by mechanical or thermal deformation, in particular a permanent deformation that occurs during or after the assembly of the contact system on a the bearing or Carrier contacting the permanent contact Contact tongue or part of the actuator introduced becomes.
- This deformation can be plastic Act deformation.
- connection between a electrical connection of the switch and the bearing can have the first section, which is approximately transverse to Direction of movement of the actuator runs. That can a second, approximately in the direction of movement of the Connect the actuator section. The first and the second section then form a substantially perpendicular molded to the direction of movement of the actuator Bulge on the support for the bearing. This bulge has an approximately U-shaped, semi-S-shaped, question mark-shaped or also S-shaped shape.
- the setting of the bearing to adjust the changeover point can be done using a tool that is on the carrier for interacts with the bearing and towards the bearing. It offers itself to design the tool in a wedge shape. To adjust the This tool is then placed approximately across the bearing Movement direction of the actuator shifted, which the Tool on the cross to the direction of movement Actuator extending first section of the carrier acts what an expansion of the bulge on the carrier Consequence. If necessary, another tool can be used a support surface can be used, the support surface during the setting on the in the direction of movement of the Supporting actuator extending second section is applied.
- the tool can also be act as an embossing tool.
- the embossing tool By means of the embossing tool at least one embossing in the carrier for the bearing recoverable. This was introduced into the carrier by the embossing Deformation causes the bearing to move to Direction of movement of the actuator.
- the bearing receiving carrier, the receiving contact Contact carrier, the gear lever or another functionally relevant component of the switch at least partially made of a thermally deformable material.
- thermal action takes place so that the Carrier, the contact carrier, the gear lever or the other Component experiences a deformation, the deformation being a Has component in the direction of movement of the actuator.
- the thermal action make single pulses of laser beams, reducing their size the deformation can be controlled in a targeted manner. Should the Effect on the carrier located inside the housing for the bearing or the contact carrier for the fixed contact or the contact tongue, so it is appropriate to the housing of the Switch on a window that is transparent to the laser beams provided.
- the Contact system is taking into account the maximum Tolerances occurring dimensioned such that according to the Assemble the contact system at the switching point at the assigned Actuating path of the actuating member initially not yet reached.
- the adjustment tool acts on the Carrier for the bearing, the contact carrier, the contact tongue or the shift lever by moving the wedge-shaped tool towards advanced transversely to the direction of movement of the actuator the embossing tool introduces appropriate embossings or thermal heating by laser beams or the like takes place. Due to these effects, a deformation takes place, the a setting in the direction of movement of the actuator causes.
- the action then continues until the Contact tongue snapped.
- the snap can be easily Way by opening, closing or switching the Contact system determine if the switch with its electrical connections when adjusting to one electrical circuit is connected.
- the adjustment process is then ended using the adjustment tool if the bearing, the fixed contact, the gear lever or another functionally relevant component of the switch one has reached the specified position. Reaching this location can by optical monitoring, for example by means of a Photoelectric sensor to be determined.
- SMD Surface Mounted Device
- the advantages achieved with the invention are in particular in that through a simple, error-prone and inexpensive arrangement the adjustment of the switching point and the difference path for the switch and the contact position or of the contact distance for the contact system is made possible.
