Handle assembly is removed. (CN.1982/1992)

Internal circuitry added to inhibit excessive pulses due to o.c. Pulse Duration switch

Changed the two internal fuse holders from “clips”, which are prone to weakening over
time to a “board mounted” type. This reduces the risk of either fuse going open circuit
which can result in overloading and failure of the remaining fuse.
