FIELD AND BACKGROUND OF THE INVENTION The present invention Impulse Switch (IS) relates to electrical switches. The electrical switch is a device operated to turn electric current on or off. Type of switches available are Push Button Switches, Roller Switches, Rocker Switches, Micro Switches, Appliance Switches, Rotary Switches, Foot Switches, Single Limit Switches, Precision Single/ Multiple Limit Switches, Inductive Proximity Switches, LT control switches, Selector Switch for NO/ NC selection. Precision Single-hole fixing/ Single Limit Switches used for control and positioning work. Precision Single/ Multiple Limit Switches used for positioning & control of machines & industrial installation. Inductive Single Limit Switches are electronic, contact less control devices for positioning, controlling & monitoring movements. Safety Switches are safety devices used for monitoring moveable guards on CNC machine tools etc. Enabling switches are manually operated control devices for use in hazardous areas of machine & equipment These switches make and brake electrical current in a circuit by making and breaking their contact by two operation of the switch. They do not turn electric current on for a moment and then made them off in one operation. They are having two positions either ON or OFF. None of the prior arts are capable of making and breaking electrical current in a circuit in one linear direction of operation. The requirement of completing an electrical circuit for a moment by turning momentarily electrical current on is achieved mechanically by inventing the present invention Impulse Switch. 3. SUMMARY OF THE INVENTION The present invention Impulse Switch (IS) is developed to meet the requirement of momentarily turning the electric current on by simply pressing a button. In the present invention the main body is made of insulating material and specially designed to meet the requirement of the present invention. Fixed contacts are fixed in the main body. There are four holes in the main body for mounting it There are two holes in it for free movement of two small size specially designed bar to cater the need of moving the moving contacts. There is one specially designed insulating material frame in which two cylindrical grooves at two opposite axial end and one rectangular cut for placing two moving contacts separated by a set of insulating separator - spring - insulating separator are made. The frame is free to move axially in the main body by pressing button or pressing a lever in one of the preferred embodiment. A small rod is passed through one axial hole in the main body. One end of the rod is inserted in the one groove in the moving frame and a button is tighten at the other end. Another small rod with head on one end is placed in the other axial hole of the main body with it's head in the other groove of the moving frame. The rod is placed co-axially inside a spring with the head touching one end of the spring. When the button is pressed or the lever is pressed in other embodiment of the present invention the small rod pushed the moving frame resulting into first closing of contacts and further pressing of the button will result in to opening of contacts pair. Thus the current in a circuit can be momentarily turned on in one linear direction of operation of the present invention. Similarly when the button is released the contact between moving and fixed contacts get closed for a moment and then open. Hence for two extreme positions of the impulse Switch the current is turned off. There are applications where momentary supply of electrical power in an electrical circuit/ system is required. In such places the use of present invention Impulse Switch will reduce the cycle of operation of the existing switch by half. 4.

FIRST EMBODIMENT Figure-] is a view of the First Embodiment of the present invention impulse Switch. Figure- la shows a top view of the present invention when the top cover 2 is removed and Figure-1 b shows axial cross sectional view of the impulse Switch. The main body 1 is made of insulating material and designed to meet the requirement of the present invention. There are four holes 19 in the bottom surface and two holes 10 in the projected end plate for mounting the Impulse Switch. There are four screwed groove 29 in the main body 1 for fixing the top cover 2 by four screws 5. Fixed contacts 21,24 and 25 are fixed in the main body. The fixed contact 25 is completely placed inside the main body. Contact terminals 8 and 6 of fixed contacts 21 and 24 respectively are projected outside the main body 1 for external connections. Terminal screws 9 and 7 are for tightening external connections. There are two holes concentric with the axis of the main body for inserting two small rods 4 and 27. Figure - 3,3a and 3b show three dimensional view, axial cross section and side transverse cut section at A - A respectively of the insulating material frame 20 of the present invention. The two moving contacts 22 and 23 are placed inside the rectangular cut in the frame 20. They are free to move inside the rectangular cut in the frame. One spring 17 is placed between the two moving contacts 22 and 23 and separated by two insulating separator 30. The spring 17 is hold in position by two insulating separator 30. The other purpose of the insulating separator 30 is to keep two moving contacts 22 and 23 electrically insulated with each other. There are two grooves cut in the frame 20 for inserting two small rods 4 and 27 in the end side. Figure - 4a shows a view of the small rod 4 and 27. These are made of metal and having smooth surfaces. The rod 4 is placed inside the hole in the main body 1 and is free to slide axially. There is one circumferential groove cut in the rod 4 for putting locking washer to prevent coming out of the rod 4 from the main body 1 after fitting the frame 20. The rod 27 is having a head in one end for giving a seating plane for the spring 26. Figure - 4b shows view of the fixed contact 25, moving contact 22 & 23 and insulating separator 30 of the present invention. The fixed contact 25 is U type with three projected parts for fixing it in the main body 1 and two holes for riveting contact tip 31. Similarly there are three holes in the moving contact 22 & 23 for riveting contact tip 31 and one hole 18 at the centre for placing insulating separator 30 in it There are two contact pairs and they are in series. Such feature is not available in any prior arts. One contact pair, fixed contacts 21 and 25, is in close condition due to touching of moving contact 22 to them and the other contact pair, fixed contacts 24 and 25, is in open condition because the moving contact 23 does not touch them. Hence the Impulse Switch is in OFF position. Now the button is pressed slowly. The moving contact 22 will not open contacts 21 and 25 due to spring 17 is softer than the spring 26. The moving contact 23 touches the contacts 24 and 25. Thus the Impulse Switch is in ON position. Further pressing of button 3 will open the contacts 21 and 25 due to movement of moving contact 22 away from the fixed contacts 21 and 25. Thus the Impulse Switch is in OFF position again. The reverse process will follow when the button is released. Hence the present invention Impulse Switch is a device which turns on the electric current for a moment only. B. SECOND EMBODIMENT The Second Embodiment of the present invention Impulse Switch is similar to the First Embodiment with a minor difference in the mechanism of pressing the small bar 4. Figure-2 is a view of the Second Embodiment of the present invention Impulse Switch. Figure- 2a shows a top view of the present invention when the top cover 2 is removed and Figure- 2b shows axial cross sectional view of the Impulse Switch. The Second Embodiment is exactly similar to the First Embodiment except a lever mechanism instead of a button 3 is used for pressing the rod 4. Lever mechanism consists of a lever 11, wheel 16 and frames 13 and 15. The lever 11 is pivoted at pivot 12 on the frame 13. The wheel 16 is free to rotate on the shaft 14. The shaft is supported on the frame 15 which is fixed on the lever 11. The rod 4 is pushed by moving the lever 11 by pressing the wheel 16. The frame 20 gets pressed as in the First embodiment of the present invention mere by making and breaking the current. The frame 20 gets released by releasing the lever 11. C. FURTHER EMBODIMENT In the further embodiment of the present invention Impulse Switch the number of Terminals can be more than two. The mechanism for pressing the rod 4 can be different from that shown in the First and Second Embodiment of the present invention. 3o^/t>C O^A/ ABSTRACT An Impulse Switch is an electrical switch to turn electric current on for a moment by pressing it's button.
