Definitions
- the invention relates to a pressure switch, in particular for writing tools and similarly shaped tools.
- Various pressure switches are known for this type of tool, but they have the disadvantage that the pressure must often be applied in a confined space.
- the invention has for its object to develop a pressure switch that does not have this disadvantage, is simple and inexpensive.
- FIG. 1 A possible application of the pressure switch and its mode of operation is shown using the examples of two writing instruments in FIG. 1 and in FIG. 2.
- the insertion elements (4) move between the sliding bodies (3), which are arranged on a fixed or movable support (1, 2) and in the rest position by elastic means (5) or magnetic Funds are pushed together.
- the side pressure is converted into a linear movement and forwarded via a connecting piece (12) to a contactor (9) which has an adjustable signal pickup (6) for
- Pressure counter, timer, acoustic signal generator, electrical signal generator, visual display, valve or mechanical switch activated can be located directly on the respective tool or somewhat outside.
- the movable carrier (2) is moved during the side printing onto the flexible cover, which can also contribute to fulfilling some of the functions mentioned.
- it can be used to block writing or for direct drawing if the pressure is adjustable
- the use of the pressure switch allows in many cases, for example on writing instruments, to draw attention to the type of tool holder in a simple manner. On the other hand, it can easily be switched on and off.
