Normally open contact: It is in the closed state when the coil is energized, and is in the open state when the coil is powered off.
Normally closed contact: It is in the closed state when the coil is de-energized, and is in the off state when the coil is energized.
Electromagnetic relays are generally composed of a core, a coil, an armature, a contact spring, and the like. As long as a certain voltage is applied to both ends of the coil, a certain current flows in the coil, thereby generating an electromagnetic effect, and the armature will absorb the pulling force of the return spring against the iron core under the action of the electromagnetic force attraction, thereby driving the armature. The moving contact is in contact with the stationary contact (normally open contact). When the coil is de-energized, the electromagnetic suction force also disappears, and the armature returns to the original position at the reaction force of the spring, so that the movable contact is attracted to the original static contact (normally closed contact). This is sucked and released, thereby achieving the purpose of turning on and off in the circuit. For the "normally open, normally closed" contact of the relay, it can be distinguished as follows: a static contact that is in an open state when the relay coil is not energized, called a "normally open contact"; a static contact that is in an on state It is a "normally closed contact".

Hans 6" and 8" Diamond Disc and Laps is the perfect tool for the commercial cutter or serious hobbyist. Diamond top plates just 1.0mm thickness is easy to apply to backing plates. All diamond top plates can come with PSA, Magnetic and Without Backing. Diamond discs are available in a wide range of mesh sizes for rough grinding and fine grinding of all precious gem material applications include performing rough and fine grinding on faceting material plus general lapidary grinding when precision is required. A controlled concentration of diamond bonded onto a precision backing plate ensures consistent grinding and surface finishes. Diamond discs can put on a precision ground.
10 inch to 24 inch Diamond Magnetic Disk was a very rough diamond used for heavy removal of glass from surfaces. It will create significant edge chipping that will need to be cleaned up with a rough to medium grit diamond disk. Disks are magnet backed for easy application and removal on lap grinder wheel heads.
Hans Diamond Pattern Disks are an electroplated diamond disk with a controlled dispersion of diamonds on the surface in a pattern. In order to maintain the longevity of the diamond disk, the StarLap disks precisely place the diamonds on the disk instead of using a random dispersion like our own electroplated diamond disks. This gives a consistent grind on your glass by controlling the spacig between the diamonds and allows a slightly longer lifespan on the disk as the diamonds maintain more space between them and support the glass less.
Diamond Standard Faceting Laps
The standard is designed to exceed the most rigid requirements. The aluminum backs are ground flat and parallel to exacting standards. All standard discs are made with 100% diamond and bonded with a hard electroplated nickel. Comes with 1/2" arbor. Screwbacked discs also available.
Diamond Channel Faceting Laps
These discs have a uniquely shaped working surface of randomly interspersed islands. The resulting channels flush away debris and prevent the stone from pulling excessively on the lap. These are great for rough cutting facets and grinding cabochon backs.
Diamond Rippled Faceting Laps
The rippled diamond laps have a textured surface that allows more contact of the diamond surface because the debris is whisked away through the channels. Each rippled diamond top plate is professionally bound to an aluminum master lap.
