Abstract

A safety device for control of working apparatuses, e.g. presses, for which start and operation modes depend on essentially simultaneous activation of two separate operating devices, which are each controlled by the respective hands of the operator. Each operating device consists of two separate push buttons. The push buttons are arranged in a housing at a mutual distance from each other, which requires a two-hand operation, e.g. with at least two fingers. The push buttons are situated at a distance from each other.
