Abstract: PCT No. PCT/GB91/00699 Sec. 371 Date Feb. 12, 1993 Sec. 102(e) Date Feb. 12, 1993 PCT Filed Apr. 26, 1991 PCT Pub. No. WO92/20206 PCT Pub. Date Nov. 12, 1992.A removable electrical unit 20 is described which incorporates a soft stop and releasing mechanism which is employed to prevent removal of the unit from its housing in an unsafe manner. In operation, the unit is pulled from the housing by means of a front handle 22 on the unit and when the unit is partially removed from its housing a stop block 72 on the unit engages a stop spring 90 on the housing. A second handle 30 on the top of the unit becomes accessible and is actuated to disengage the stop block and stop spring. The unit may then be completely removed from the housing in a safe two handed manner.
