MACHINE WITH MECHANICAL DRIVE WITH ON-OFF MECHANISM

摘要

FIELD: machine building. ^ SUBSTANCE: invention refers to power cutoff switches for machines with mechanical drive. Machine with mechanical drive that has on-off mechanism includes housing with supporting surface, control unit connected to supporting surface. Control unit has positions "off", on without interlock" and "on with interlock". Machine also contains device for control unit contraction into position "off" from position "on without interlock". Control unit has first pressure surface for its manual movement from "off" position into "on without interlock" position against contraction means action and second pressure surface for its manual movement from "on without interlock" position into "on with interlock" position. First pressure surface and second pressure surface are adjacent ones and form an angle exceeding 180. ^ EFFECT: safety increase provision. ^ 14 cl, 10 dwg
