PCT No. PCT/SE92/00720 Sec. 371 Date Apr. 20, 1994 Sec. 102(e) Date Apr. 20, 1994 PCT Filed Oct. 14, 1992 PCT Pub. No. WO93/09377 PCT Pub. Date May 13, 1993.The invention relates to a safety switch intended to be connected into a safety circuit for an industrial machine, for example an industrial robot. The switch comprises a contact device (2) with a hand-operated device (3, 4) in which a pressure rod (31) is displaceable against the action of a return spring (33) from a first end position via an operating position to a second end position, the safety circuit being closed only in the operating position. During the return movement of the pressure rod from its second to its first end position, the contact device (2) is not affected, and the safety circuit thus remains open during the whole of this return movement. |
