Abstract: A monitoring module for a fusible switch disconnect device includes an open fuse detecting element and wire leads for completing an electrical connection with a fuse.
Abstract: A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to displace the switchable contact, as well as multiple other components in the device, in response to a predetermined electrical condition.

Abstract: Fuse state indicators for use with disconnect devices having a fuse are provided. Fuse state indicators include a housing having circuitry, a detecting means for detecting an open circuit condition, conductors adapted for electrical connection to a disconnect device so as to complete a circuit connecting the detecting means with a fuse of the disconnect device, and a signal transmitting means The detecting means is configured to transmit a signal to the signal transmitting means for determining an operational state of the fuse. The signal transmitting means, in turn, is configured to transmit a signal to a remote device the state of the fuse.

Abstract: A safety press-button switch includes a linkage formed of a lever and a switching rod pivoted together, and a press-button cap having a push rod and a hook arm respectively aimed at the switching rod and a positioning rod of the lever and adapted to force the lever to shift a bimetal plate from OFF position to ON position and to hold the lever in position after the bimetal plate switched on, the positioning rod of the lever being forced away from the hook arm by the deformation force of the bimetal plate for enabling the bimetal plate to trip off automatically upon an overload.
