摘要： A contactor assembly is adapted for switching power to a circuit having a power source. The contactor assembly includes a housing, carry contacts, and arc contacts. The housing defines an interior compartment and includes internal chamber walls that laterally extend within the compartment to define a protection chamber. The carry contacts are disposed in the protection chamber of the housing. The carry contacts include conductive bodies that protrude from the housing and are configured to close the circuit. The arc contacts are disposed in the housing outside of the protection chamber. The arc contacts include conductive bodies that protrude from the housing and are configured to close the circuit. The internal chamber walls of the housing prevent material that is expelled from one or more of the arc contacts when an electric arc emanates from one or more of the arc contacts from contaminating one or more of the carry contacts.

摘要： Disclosed a trigger switch including fixed contacts forming main contacts double in series and functioning as a switch for supplying a motor with power and slide plate parts connected to the fixed contacts; and movable contacts provided in an actuator interlocking with an operation part and auxiliary contacts sliding on the slide plate parts. Drawing the operation part causes the actuator to move forward making the movable contact come into electric contact with the fixed contact to supply the motor with power, simultaneously making the auxiliary contact bridge over the slide plate parts to achieve electric contact to make no potential in the contact between the movable contact and the fixed contact. Releasing the operation part make the movable contact separate from the fixed contact, simultaneously making the auxiliary contact bridging over the slide plate parts cause a break of the contact with the slide plate part.

摘要： A method of forming a switch assembly that includes a magnetic intensifier constructed to extend in generally close proximity to one of the stationary contact and the arc contact. During communication of power through the contactor assembly, the magnetic intensifier manipulates a magnetic field associated with current passing through the switch assembly and increases the magnitude of a magnetic force directed to the arc arrestor. Preferably, the magnetic intensifier is formed integrally with a turnback associated with one of the stationary contact or the arc contact. Such a construction simplifies the manufacture and assembly of the contactor assembly and provides efficient and repeatable arc suppression.

摘要： Provided is an electromagnetic relay which does not require a braided wire for securing a current capacity of a main contact unit. The electromagnetic relay includes a main contact unit inserted into a power supply path to a load and an arc contact unit connected in parallel to the main contact unit. An auxiliary contact unit is electrically independent of the main contact unit and the arc contact unit. The main contact unit includes a main fixed contact fixed to a frame body and a main contact spring made of a leaf spring and fitted with a main mobile contact which is attached to and detached from the main fixed contact. The arc contact unit and the auxiliary contact unit are arranged adjacent to each other. The main contact spring extends in a direction in which the arc contact unit and the auxiliary contact unit are arranged. Therefore, the main contact spring can be formed with a large length in the frame body and the sectional area can be enhanced without increasing a spring constant, thereby not requiring a braided wire.
