Double and Triple Push Buttons

A double control push button (twin button) is a button that combines two separate spring-return keys in a single housing that fits one 22 mm mounting hole; on triple models a third key is added to this housing. It is used in motor control circuits where two complementary commands, such as start and stop, are to be given while taking up little space on the panel surface. The category includes models with green-red and black-white keys, 1NO + 1NC contacts, flush or protruding keys, non-illuminated and illuminated with 24 V AC/DC or 220 V AC, from the brands EMAS, Isıso and Gwest. Select the key colors, contact arrangement, protruding or flush key design, lamp voltage on the illuminated model, and plastic or metal housing to suit your control circuit. A double button should not be confused with a two-gang push button enclosure into which two separate buttons are fitted; both keys are in a single housing and a single mounting hole.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
