Definitions

  • the invention relates to a device for mechanically securing the ON and OFF switch position an electrical pressure switch.
  • EP 0 702 381 already describes a device for mechanically securing a Switch position of an electrical pressure switch known that either only the fuse ON switch position or in another embodiment after replacement Functional parts to secure the OFF switch position.
  • the invention has for its object a device of the type mentioned to make available a simultaneous ON and OFF switch position protection without Switch modification in low-parts version available for all common switches.
  • the invention accordingly advantageously makes a new device at the outset mentioned type available, in which both the ON and OFF switch position assurance are summarized in a functional part. It will be for the unlocking and locking required only two parts at the same time, and the complex assembly there is no additional lever as in the prior art. Another advantage is that both the ON and OFF switch position protection via one and the same locking button take place without the need to change hands.
  • the electrical pressure switch has a switch in its switch housing Release preloaded hollow push button to produce a electrical contact, in which also contact and undercut Locking profile arrangements are formed. Furthermore, one is shown in alignment Locking button provided, which is connected to a fork-shaped slider, which for each system and locking profile arrangement inside the push button a leg 2 from below into these protruding angled tines with complementary has profiled ends.
  • This makes it easy to secure the OFF switch position in the disengaged position of the locking button and securing the Realize the ON switch position in the inserted position of the locking button, the ON switch position undercut by mutual engagement or against Direction of disengagement of inclined mutual locking surfaces of locking profile and complementary tine profile end against the release force of the spring for the Locking button is realized.
  • This solution has the advantage that a Pushing the pushbutton in a simple way the safety switch canceled due to the bias of the locking button and securing the OFF switch position can be reached.
  • each points in the disengaging direction seen front tines on a stepped profile end, on in the disengaging direction Release limit stop and a downward inclined counter to the release direction Locking surface for securing the ON switch position are formed.
  • the arrangement is preferably taken so that the usual roughness and inclination of everyone undercut locking surface and each locking profile against the disengagement direction and measure the strengths of the release spring for the slide and the push button are that the locking surface of each front tine in the ON switch position is safe and at larger vibrational loads on the locking profile remains.
  • the release limit stop on the front tine is according to a further embodiment
  • the tines in the disengaging direction to secure the OFF switch position point preferably a final contact surface that is perpendicular to the direction of actuation of the push button for contacting extends through the system profile arrangement.
  • the contact surface of the rear tine is only in the path of movement of the Push button, but does not have to rest on the system profile.
  • the distance between the tines is from one another dimensioned such that when the front tine in the disengaging direction lies against the edge of the Push button the contact surface of the rear tine slightly below the Investment profile arrangement lies.
  • the system and locking profile arrangements are preferably in the area of the central axis of the Push button, preferably formed in opposite edge areas to the to distribute the mechanical loads attacking the push button symmetrically and to design its guide in the housing without canting and thus with little wear.
  • FIG. 1 to 4 show an exemplary embodiment of a device 10 for mechanical Securing the ON and OFF switch position of an electrical pressure switch 11 shown schematically in a partially sectioned side view.
  • a switch housing 12 In a switch housing 12 is a hollow push button 13 in a manner not shown for a linear movement performed and can not from the position shown in Figure 1 against the action of a Spring shown for making an electrical contact, not shown be pressed in if no OFF switch position protection is active.
  • FIG. 2 there is a locking button 14 guided perpendicular to the direction of actuation of the push button 13 in the housing 12.
  • the locking button 14 is biased by a compression spring 15 in the disengaging direction and has a cranked fork-shaped slider 16.
  • the slider 16 has two legs 17 and 18 spaced from each other protrude from each leg 17 and 18 angled tines upwards into the interior of the hollow push button 13.
  • Tines 19 and the rear tine 20 are shown, while FIG. 1 shows only the direction of disengagement represents front prongs 21.
  • the tines 19 and 21 have a gradation in the region of their upper end a lateral release limit stop 22 or 23, which points in the release direction and is provided for contact with the lower inner edge 24 of the hollow push-button 13.
  • the tines 19 and 21 have a downward inclination Locking surface 25, which serves to secure the ON switch position of the pressure switch.
  • the Tine 20 has an end-side contact surface 26, which is used to secure the OFF switch position is provided, as will be explained below.
  • a transverse wall 27 is formed, the Push button 13 divided into two halves and a complementary edge Has locking profile 28 or 29 in the form of an opening, the lower edge 30, see figure 2, complementary for the locking engagement with the locking surface 25 of the tine 19 trained, i.e. has the same inclination. If the contact surface 25 of the tine 19th is arranged on the locking profile surface 30 of the intermediate wall 27, the switch in the ON switch position actively secured, as shown in Figure 4, with the rear tine 20 freely in the inside of the push button 13 protrudes.
  • FIGS. 2 to 4 Various switching states are shown in FIGS. 2 to 4 for explanation.
  • figure 2 is the upper contact surface 26 of the tine 20 below one at the lower end of the Partition 27 formed contact surface 31 and is in this position by contacting the Contact surface 22 on the lower inner edge 24 of the push button 13 under the effect of Preload spring 15 held. This ensures safe compliance with the OFF switch position reached.
  • FIG. 3 shows an intermediate position of the locking button 14 together with the slide 16 shown, in which the tines 19 and 20 with the molded on them and Locking surfaces can freely enter the inside of the push button 13.
  • the Pushbutton 13 can be free in this position to make an electrical contact be indented.
