Abstract

The safety device contains a first unit (1) with a closure body which can be fitted to the machine frame, and a second unit (5) which can be fitted to a protection device (7), for example a door, and has a closing part (9). The closing part can be moved from an open position into an off position and into an on position and, in the open position, can be engaged with the first unit and disengaged from it. The closing part operates a switching device (29) when both units are engaged with one another, in such a manner that the voltage is applied to the machine only when the closing part (9) is in the on position. A delay device (30, 31, 32, 34), which can be actuated from the on position into the off position by rotating the closing part (9), prevents displacement of the closing part from the off position into the open position during a time interval in order, for example, to block access to the machine before it stops. The device can be used, for example, on a domestic spin drier. <IMAGE>
