Abstract
A telephone junction box has two or more switches each of which comprises two resilient conductors that can be sprung between a first configuration in which they are in electrical contact and a second configuration in which they are separated. The conductors preferably include insulation displacement means.
Claims21
An electrical switch which comprises:
- (a) a resilient first conductor to which a first wire can be electrically connected;
- and
- (b) a resilient second conductor to which a second wire can be electrically connected;
- the switch is capable of having two stable configurations in the absence of continued interaction by a third body, namely;
- (i) a first stable configuration in which the first and second conductors are held in electrical contact at least in part by the resilient bias of the first and second conductors;
- and
- (ii) a second stable configuration in which the first and second conductors are held apart at least in part by the resilience of the first and second conductors, configuration (ii) being reached from configuration (i) at least in part by the relaxation of said resilient bias and the rotation of at least one of said first and second conductors about an axis located between the first and second conductors in configuration (i), and wherein the axis is substantially perpendicular to the force exerted between the first and second conductors when in configuration (i).

A telephone junction box for interconnection of electrical wires, which comprises:
- (i) a housing;
- (ii) at least four contacts to which four wires can be connected;
- and
- (iii) at least a first and a second bi-stable switch within the housing each of which first and second switches can independently make and break a connection between a pair of contacts, wherein each bi-stable switch is capable of operating in a connected or a disconnected condition in the absence of a continued action by a third body.

A two-part bi-stable switch, which comprises:
- (a) a first resilient conductor to which a first wire can be connected;
- and
- (b) a second resilient conductor to which a second wire can be connected;
- said second conductor having substantially similar size and shape to the first conductor, and being positioned relative to the first conductor such that the switch has substantial planar or rotational symmetry;
- and
- the switch is capable of having two stable configurations, in the absence of a continued action by a third body, namely:
- (i) in which the conductors are relaxed and are not in contact with one another;
- (ii) in which the conductors are deformed against their resilience to cause a resulting resilient bias between a part of each conductor to be forced against a corresponding part of the other.
