Abstract

A modular receptacle includes opposing contacts as well as receiving portions. The receptacle slidably receiving a switch or plug therein. The switch or plug having opposing contacts which contact the opposing contacts on the receptacle and also having indented and protruding portions which cooperate with the receiving portions in the receptacle. Thus, switches or plugs can be selectively removed or inserted from the modular receptacle without the need to remove the receptacle from a wall on which the receptacle is mounted.

Claims

1. A modular pull-out assembly comprising:

a receptacle having first and second opposing walls which comprise opposing electrical contacts, one of said first and second opposing walls comprising a ground means, the receptacle further comprising opposing third and fourth walls each having receiving portions which extend substantially along a length of each of said third and fourth walls; and

at least one switch or plug which is removably inserted into said receptacle;

wherein;

said at least one switch or plug comprises first and second opposing surfaces with opposing electrical contacts and a ground, a third surface with an indented portion and a fourth surface opposed to said third surface with a protruding portion, the switch or plug being removably slidable into the receptacle such that said opposing electrical contacts on said first and second walls of said receptacle respectively contact said opposing electrical contacts on said first and second opposing surfaces of said switch or plug, and one of said indented or protruding portions on said third and fourth surfaces of said switch or plug is respectively slidably fitted on one of said receiving portions on said third and fourth walls of said receptacle.

2. A modular pull-out assembly according to claim 1, wherein a plurality of said switches or plugs are inserted into said receptacle, said first and second opposing walls of said receptacle each comprising a plurality of opposing electrical contacts which contact opposing contacts on each of said plurality of switches or plugs inserted in said receptacle, each of said plurality of switches or plugs comprising said opposing protruding and indented portions such that a protruding or indented portion on one switch or plug is slidably fitted onto a protruding or indented portion on an adjacent switch or plug, and protruding and indented portions on outermost switches or plugs which face said first and second opposing walls of said receptacle are respectively slidably inserted on said receiving portions on said opposing walls of said receptacle.

3. A modular pull-out assembly according to claim 1, wherein said receptacle includes an elongated projecting member positioned at a center of said receptacle and having an end portion with a hole therein which permits the insertion of a screw for holding a top plate on said receptacle.

4. A modular pull-out assembly according to claim 1, wherein said at least one switch or plug comprises at least one switch, said at least one switch including:

first and second levers which each extend from said electrical contacts toward a center portion of the receptacle, edge portions of said first and second levers overlapping each other and maintaining a predetermined spacing therebetween;

a switch lever which is pivotally mounted on said switch, said switch lever having a wedge portion which during a pivoting movement of said switch lever pushes down one of said first and second levers so as to make contact with the other of said first and second levers.

5. A modular pull-out assembly according to claim 1, wherein said at least one switch or plug comprises at least one plug, said at least one plug comprises a positive inlet, a negative inlet and a ground, said plug further comprising leads which extend from each of said contacts to springs positioned in said plug so as to correspond to said positive inlet, said negative inlet and said ground.

6. A modular pull-out assembly comprising:

a receptacle having first and second opposing walls which comprise opposing electrical contacts, one of said first and second opposing walls comprising a ground means, the receptacle further comprising opposing third and fourth walls each having receiving portions which extend substantially along a length of each of said third and fourth walls; and

at least one switch or plug which is removably inserted into said receptacle;

wherein said receptacle includes an elongated projecting member positioned at a center of said receptacle and having an end portion with a hole therein which permits the insertion of a screw for holding a top plate on said receptacle.
