185 Switch for vehicle US11869982 2007-10-10 US07579568B2 2009-08-25 Yoshiyuki Nakade
In the switch, a terminal section and a contact section of a fixed contact are separately formed and the two sections are connected via a coil made of a conductive metal wire. After electrical connection is established between a movable contact and fixed contacts, a weak current with no arc discharge flows between the movable and the fixed contacts. This prevents build-up of oxide or carbide on the contact surface, allowing the switch to have stable contact operation and accordingly reliable electrical connection.

191 Bayonet-type fuse and fuseholder assembly US948663 1992-09-22 US5227758A 1993-07-13 Radhakrishna Ranjan
A tubular fuseholder housing carries two sets of generally-stationary contacts located at points spaced apart along the length of the housing. Within the housing is a fuse comprising a cartridge and, at opposite ends of the cartridge, terminal contacts for respectively engaging the stationary contacts when the cartridge is fully inserted into the housing. An insulating operating rod within the fuseholder housing is coupled to the fuse cartridge and extends toward the outer end of the housing.Actuation of the operating rod separates the terminal contacts from the generally-stationary contacts and draws electric arcs between these contact. Closely adjacent the individual contacts of each set of stationary contacts and angularly aligned with the individual contacts, supplemental exhaust ports are provided in the fuseholder housing. The fuseholder housing normally contains dielectric liquid covering the fuse which is vaporizable by the arcs to generate gases that are exhausted through the supplemental ports. Actuation of the fuse cartridge from its fully-inserted position toward its disconnected position produces a pumping action within the fuseholder housing that forces liquid within the housing through the regions of said arcs and out the supplemental ports.

The pyrotechnic isolating apparatus (1) for isolating a conductor (8) using an isolating punch (14) has a housing, in which the isolating punch (14) is routed, and an ignition unit (6) for driving the isolating punch (14). According to the invention, a quenching means (13) for suppressing or quenching an arc is arranged between the isolating punch (14) and the ignition unit (6). Therefore, the quenching means (13) also transmits the drive force to the isolating punch (14).
