A thermal overload mechanism for providing protection to tip and ring conductors in a telecommunications system in the event of a power cross occurrence of telephone lines with power lines. The thermal overload mechanism includes a clip having front and rear spring members dimensioned for seating about a spacer element. The spacer element includes one or more recesses defined therein for accommodating securement of solid state devices. The recesses formed in the spacer elements contain a breachable membrane or wall which is breakable in the event the membrane temperature exceeds a predetermined temperature such as a temperature occurring in the event of a power cross situation. A contact configured for seating within the recess between the membrane and solid state device is provided for maintaining electrical contact with the tip and ring wires. During a power cross situation, high current causes the temperature of the solid state devices increase, thereby causing a breach of the membrane and providing a direct grounding path for the tip and ring wires through the rear spring and common ground.

A switch module applied for a power supply system is disclosed. The switch module comprises a power switch, an insulating member, a surge absorber and a pyrocondensation belt. The power switch is connected with the power supply system, the insulating member is set on the power switch, the surge absorber is electrically connected with the power switch and adjacent to the power switch, the pyrocondensation belt is connected with the surge absorber and the insulating member. The pyrocondensation belt shrinks with a temperature of the surge absorber. When the insulating member is in the initial state, the insulating member does not affect the power switch. The insulating member makes the power switch off when the shrinkage degree of the pyrocondensation belt develops enough to block the power switch from being on.

Disclosed herein are efficient mechanical fuse devices that are capable of functioning at high current levels. These devices comprise mechanical features configured such that the fuse devices have a non-triggered state, which allows current to flow through the device, and a triggered state, which does not allow current to flow through the device. In some embodiments, the devices are configured such that a certain pre-determined current level flowing through the device will generate a sufficient electromagnetic field to cause the mechanical elements to transition the fuse device into the triggered state and thus interrupt a connected electrical circuit, device or system. In some embodiments, these devices can also comprise hermetically sealed components.
