Push switch

Abstract

This invention relates to a push switch, mainly comprising a push assembly, a base, and a terminal group. The push assembly includes a rotary isolating mechanism, which includes a rotary isolating element disposed between the sleeve and the rod, allowing the push part to rotate relative to the internal structure during operation. The torque generated by the rotation is not transmitted to the internal actuating structure. Thus, even if the user rotates the push switch during the pressing process, the internal components will not be damaged by torsion, while maintaining stable conduction during pressing. Through the above structural configuration, the durability, operational stability, and service life of the push switch can be effectively improved.

Claims

1. A push-button switch, comprising a push-button assembly, a base, and a terminal group, wherein: The pressing assembly comprises a pressing member, a pushing member, and a sleeve. The pressing member has a rotating isolating mechanism. A rod is provided on the main body of the rotating isolating member, which passes through the shaft hole of the rotating isolating member. A stop member is assembled on the rod to restrict the movement of the rotating isolating member. A sleeve extends downward from the main body to accommodate the head of the pushing member. The rotating isolating member is covered by a sleeve that accommodates the rotating isolating member and the stop member. A tube with a smaller outer diameter extends downward from the head. The tube has at least one clamping groove on the side away from the head. A first elastic element is sleeved on the tube. The sleeve has a through hole that passes through both the upper and lower sides and allows the pressing member and the pushing member to pass through. The base has a base and a cover. The base has an accommodating space for the bottom side of the tube of the pressing component to pass through. A second elastic element is sleeved on the bottom side of the tube in the accommodating space. A plurality of slots are recessed on one side of the base. The cover has an insulating plate assembled on the top surface of the base and an iron sheet assembled on the top surface of the insulating plate. An insulating flange with a pair of positioning holes is provided on the top surface of the insulating plate, and a positioning space is formed below the insulating flange. The terminal assembly has a contact piece and a plurality of terminals. The contact piece has a clamping groove assembled on the side of the tube body and has at least one contact end on the side of the contact piece facing the slots. The terminals are each disposed in the slots and have a conductive portion extending towards the contact end. The terminal has a connecting end extending out of the base body on the opposite side of the conductive portion. When the pressing member is pressed and rotated, the rotation isolation member can prevent the torque generated by the rotation from being transmitted to the rod and the pushing member.

2. The push switch as described in claim 1, wherein the stop member has an engaging portion extending inwardly on both sides.

3. The push switch as claimed in claim 1, wherein the bottom of the cylindrical portion extending downward from the body is provided with an assembly groove for receiving the head of the pusher.

4. The push-button switch as claimed in claim 1, wherein the bottom of the sleeve is provided with a receiving groove for accommodating the rotating isolator and the stopper.

5. The push-button switch as claimed in claim 1, wherein the top surface of the conductive portion of the terminal group is provided with a contact surface, and the contact surface extends downward with a reinforcing edge to increase the force point, and the base is provided with a pressing surface that is slightly higher than the height of the contact surface of the terminals.

6. The push switch as claimed in claim 1, wherein the bottom of the pressing member has a receiving groove for receiving the head of the pushing member, and the top surface of the head has a pushing surface, and the bottom surface of the head has a supporting portion for the first elastic element to support.

7. The push switch as claimed in claim 1, wherein the outer wall of the sleeve is provided with a plurality of external threads, and at least two fixing nuts are further assembled on the outside of the sleeve, and the two fixing nuts are provided with a plurality of internal threads that surround the wall and engage with the external threads.

8. The push-button switch as claimed in claim 1, wherein the bottom side of the sleeve is provided with an assembly flange with a smaller outer diameter, and the top surface of the iron sheet is provided with an assembly part for assembling the bottom side of the sleeve, and the assembly part is provided with a limiting hole through which the assembly flange of the bottom side of the sleeve passes and is positioned around the insulating flange.

9. The push-button switch as claimed in claim 1, wherein the top surface of the base is provided with a plurality of fixing holes, and the insulating plate is provided with a plurality of first through holes aligned with the fixing holes, and the iron sheet is provided with a plurality of second through holes aligned with the first through holes, and each of the second through holes is for a fastener to pass through and be locked into the fixing hole via the first through hole.
