| description | The utility model discloses a non-contact safety switch and a cigarette maker; the non-contact safety switch comprises an inductance type detector (8) and a relay (8); the inductance type detector (8) is used for monitoring close or open states of a leveling device protection door (2); a coil of the relay (10) is connected with an output end of the inductance type detector (8); one end of a normally open contact (11) of the relay is connected with a control power supply end, and the other end of the normally open contact is connected with an enable relay (7) and used for controlling the enable relay 7 to be electrified or disconnected; one end of a normally close contact (12) of the relay is connected with the control power supply end, and the other end of the normally close contact is connected with a PLC input point and used for controlling whether to generate a signal indicating the open state of the protection door. The non-contact safety switch and the cigarette maker are hardly affected by smog dust, an |
