Abstract: An electromagnetic opening/closing device comprises: a measurement part that measure a change associated with opening/closing of a contact (the number of times the contact has been opened or closed); a life determining part that determines a state of the contact, based on the change (the number of times the contact has been opened or closed) measured by the measurement part; and an output part that outputs the determined result by the life determining part to outside. Accordingly, differently from the conventional technique, an apparatus, equipped with the electromagnetic opening/closing device, has no need to count the number of times the contact has been opened or closed in order to manage the lifetime of the device, and it is possible to easily manage the lifetime compared with conventional devices.

Abstract: The present invention discloses a timer switch that uses an integrated circuit to control the time and a self-locking electromagnetic coil solenoid valve to drive the operation of a microswitch, which is particularly applicable to be installed on a wall as a timer switch. The switch device uses the electronic control of two 1.5V AA batteries to enter a set time through input keys, and a CPU will issue a pulse with very short timing of 30 ms to the solenoid to produce a magnetic field to drive a turning rod and open a primary switch in order to turn on or off a circuit.

Abstract: An auxiliary contact device is taught for utilization with a motor controller or a contactor. A linear cam arrangement is utilized with a rooted flexure arm to cause the contact end of the flexure arm to move in relationship with the linear travel of the stroker carrying the cam surface into a disposition of electrical continuity with a fixed contact. Subsequent linear movement of the stroker in the same direction continues to move the cam surface thereof over an offset in the flexure member after contact has been made. This causes a wiping action between the abutting contact surfaces. The arrangement may be utilized in either the normally open or normally closed disposition. It may be used on multipole devices and the stroker member may be modified for matching a common auxiliary contact assembly arrangement with various kinds of main contactors or controllers or to change timing of contact status change.

Abstract: A mechanical latch attachment (20) for a control relay (21) includes a mechanical latch movement (77), a solenoid (49), and a pair of contact cartridges (33) that are disposed in a housing (25). The wear-resistant latch movement (77) has a latch (95) with teeth (103) on one end that are engaged by a pair of pivotable, hooked pawls (105). The latch (95) is coupled to an operating plunger (79) through a contact actuator (82). The operating plunger (79) can be coupled to a conventional control relay (21), which moves the plunger (79) upon the closing of its relay armature (30) to actuate the contacts (35, 36) in both the relay (21) and the attachment (20) and to move the latch (95) to a position where it is restricted by the pawls (105). The restriction of the latch (95) holds the relay armature (30) closed and the contacts (35, 36) actuated even though the relay (21) is deenergized. The solenoid (49) has an armature (62) that can be moved mchanically or electrically to release the latch (95) from the pawls (105). A high-compression spring (89) coupling the plunger to the contact actuator (82), protects the latch movement (77) from shock forces that might be encountered during shipment or abnormal handling. Relays with a mechanical latch attachment provide quiet operation and retain their operated state even in the event of a power failure.

Abstract: Electromagnetically operated contactor employing contact modules which are converted from normally open to normally closed and from normally closed to normally open operation by inverting the contact module in the contactor. The contact terminals of the contact module are clamped by various arrangements against conductive members of the contactor. Wiring terminals for connecting external wiring to the conductive members are spaced from the arrangement for clamping the contact terminals to the conductive members. Thus, the wiring terminals and the external wiring do not interfere with the module or arrangement for clamping, and the module may be removed, inverted, and replaced without disturbing the external wiring connections.
