Product Overview

The Micro Switch (Roller Lever) is a compact, snap-action limit switch commonly used on Power Press machines and automation equipment. It provides precise and repeatable signal output for position confirmation, top/bottom stroke limits, feeder end detection, and die safety interlocks.

Key Features

  • Roller-lever actuator for smooth contact with cams or moving parts.
  • Snap-action contacts ensure crisp, reliable switching.
  • Compact housing and universal mounting slots for easy retrofit.
  • High electrical rating suitable for control circuits and relays.
  • Durable construction for long service life in industrial environments.

Typical Applications

  • Press TDC/BDC confirmation and stroke limit detection
  • Die protection (part out / eject confirmation)
  • Feeder in-position / end-of-stroke sensing
  • General machinery interlock and counting signals

Suggested Specs (Reference)

  • Contact rating (typical): 250VAC 10A / 125VAC 15A / 14VDC 15A
  • Contact form: SPDT (COM/NO/NC)
  • Actuator: Roller lever, snap action
  • Mounting: Through-hole / slotted
  • Terminals: Screw or quick-connect (model dependent)

Frequently Asked Questions (FAQ)

NO (Normally Open) closes when actuated; NC (Normally Closed) opens when actuated. Choose based on the required control logic or safety circuit.

Yes. It is commonly mounted to detect part ejection or misfeed; when triggered, it sends a stop signal via the die error detector controller.

Use a cam or flag to actuate the roller smoothly (avoid side loads), keep wiring tight, and protect the switch from oil splash and chips for longer life.
