The utility model relates to the technical field of switches, and discloses an anti-self-locking switch which comprises a shell, four wiring terminals are fixedly arranged on the shell, a button is arranged on the shell, a moving part is arranged in the shell in a sliding mode, and the moving part is connected with the button. A self-locking key is fixed on one side of the shell, a connecting rod is fixed in the self-locking key, and a locking block is fixed at one end of the connecting rod; a control block is fixedly arranged on one side of the moving part, a horizontally-arranged second spring is fixedly arranged in the control block, the two ends of the second spring are fixedly connected with limiting blocks, two blocking pieces are fixedly arranged in the shell, a locking groove is formed in the moving part, and the locking block is fixedly connected with the locking groove. When the switch is closed, the locking block is controlled to be inserted into the locking groove through the self-locking key, the interior of the switch is self-locked and fixed, the switch is always closed, the closing firmness of the switch is improved, the use safety is improved, the power failure risk is reduced, and the safety of applied equipment is protected.

The application discloses a kind of bistable press type mechanical self-locking switch, including mounting seat, plug-in rod, press lever, press handle, reset compression spring and limit ball, mounting seat is equipped with mounting seat through-hole, plug-in rod passes through mounting seat through-hole, plug-in rod is equipped with plug-in rod center through-hole, plug-in rod center through-hole is sequentially first section through-hole, second section through-hole, third section through-hole and fourth section through-hole, the hole wall of fourth section through-hole is equipped with taper through-hole along circumference, the circumferential hole wall of mounting seat through-hole is equipped with ring groove, press lever is located in plug-in rod center through-hole, one end of reset compression spring and press handle contact, the other end and the step between second section through-hole and third section through-hole contact, taper section and cylindrical section are equipped on press lever, limit ball is placed in taper through-hole.The application realizes the self-locking function of plug-in rod in insertion and pull-out two states, i.e., realizes bistable self-locking function, can effectively prevent adverse consequences caused by misoperation.

An electromagnetic-based ultrasonic residual stress relief system and process for welds on metal surfaces can include a latching switch for high voltage charging that controls current from the capacitor charging module to the high voltage capacitor, a non-latching switch for spark-gap trigger that can control current from a spark-gap trigger module to a spark-gap trigger circuit. The non-latching switch for spark-gap trigger can discharge energy from the high-pulsed current capacitor into the spark-gap circuit, which can discharge energy into a coil that can be moved over the weld zone. The large AC current induced high-frequency, small-amplitude through-thickness ultrasonic vibration yields residual stress relief in the weld and HAZ region.
