1. When the Omron switch power socket is embrittle or damaged, it must be repaired and replaced immediately.
2. When going out, falling asleep, or suddenly losing power, be sure to cut off the power immediately. Household appliances, in particular, must be more careful.
3. Omron switches and power sockets should be set in boring, cleaned, and cleaned parts as much as possible to prevent fire caused by short circuit faults of plastic hoses caused by moisture erosion in the body.
4. The power socket of the lamp port is very easy to cause malignant events when it is overweight. Therefore, high-power sockets such as irons, heating furnaces, central air conditioners, etc. should not be connected to the socket for application to prevent fire.
5. The Omron switch should choose a suitable fuse wire. It is not allowed to change at will, especially the thickened solution, and it is not allowed to replace the fuse wire with copper, aluminum, iron and other metal wires.
6. The increased current amount and increased working voltage of Omron switches and power sockets must be consistent with the specific power consumption. It is not necessary to load casually, so as to prevent the route load from damaging the bakelite powder and causing a short circuit fault and fire.
7. The Omron switch must be operated by the fire (phase) wire, and cannot be connected with the neutral line. Otherwise, if the human body touches the pile line, it will also cause safety accidents. Once the rear side is grounded, it will also cause short circuit faults and even fires.
8. The appropriate choice is to choose appropriate switches and sockets according to the total volume of electrical products and the detailed application of the natural environment. In high ambient humidity sites, fire safety switches and hanging wire switches should be selected. Omron switches and sockets should not be installed in rooms with corrosive objects or large amounts of dust, but only outdoors. Fire-safe or explosion-proof switches and sockets should be selected in areas where there is a risk of ignition and explosion.

【Omron industry case】Application case of laser die-cutting machine for secondary battery
Process introduction
In the traditional die-cutting process, because the cutter cannot cut the material completely, the connecting frame will be left, which increases the cost of the material. In addition, the service life of the die-cutting knife is 1 million times, such as long-term continuous operation, it needs to be replaced and maintained in time, and the maintenance and debugging time is also very long.
