Abstract
A combined cartridge fuse holder and switch incorporates the cartridge fuse as part of the switching mechanism. One end of the cartridge fuse is pivoted about a fulcrum contact coupled to a first terminal. A switch assembly swings the other end of the cartridge fuse transversely relative to the fuse axis to make and break contact with a contact on a second terminal.
Claims18
A combination fuse holder and switch comprising:
- body means including a first receptacle means for receiving one contact end of an elongated fuse, said body means defining a channel communicating between said first receptacle means and an opening on said body means, a first terminal associated with said body means and having a first contact in said first receptacle means, and a second terminal associated with said body means and having an arm located in said channel, said arm having a second contact therein spaced from said first contact,
- switch means including a second receptacle means for retentively receiving a second contact end of said fuse, said switch means for moving said fuse transversely relative to the longitudinal axis thereof, means for placing said second contact end of said fuse in electrical contact with the exterior of said second receptacle means,
- holder means for said switch means for coupling said switch means to said body means so that the first contact end of said fuse is in electrical contact with the first contact in said first receptacle means, the second contact on the arm of said second terminal being so positioned relative to said second receptacle means and said second receptacle means being so constructed as to make and break contact with the second end of said fuse when said second receptacle means is moved transversely relative to said fuse axis by said switch means.
A combination cartridge fuse holder and switch, for a cartridge fuse having first and second ferrule contacts on respective ends thereof, comprising:
- body means having first and second ends, said body means having a channel opening onto said first end and extending toward said second end, said second end having a cavity therein sized to receive a first ferrule contact of a cartridge fuse, one end of said cavity communicating with said channel, said body means including an end wall located at the second end of said body means, said end wall closing the other end of said cavity,
- a first terminal affixed to said body means and having a first terminal end exterior of said body means and having a cavity contact located at said other end of said cavity,
- a second terminal affixed to said body means and having a second terminal end exterior of said body means and having an arm extending into said channel said arm having an arm contact thereon located in said channel and spaced from said cavity contact,
- retention means for receiving a second ferrule contact of a cartridge fuse and mounting means associated with the first end of said body means for mounting said retention means for swinging movement from a first position adjacent said arm contact to a second position spaced from said arm contact, said retention means including means for placing said second ferrule contact into electrical contact with said arm contact when said retention means is in said first position, and
- actuating means for moving said retention means between said first and second positions.
