Waterproof Micro Switches
Waterproof Micro Switches for Position and Limit Sensing
Sealed snap-action micro switches for doors, lids, cams, pedals, and equipment interlocks. Select by actuator type, operating force, IP rating, circuit configuration, electrical load, and terminal or wire-lead option.
- Sealing Up to IP67 on selected series
- Actuators Pin plunger, hinge lever, and roller lever
- Operating force 50 to 400 gf across selected series
- Termination Quick-connect, solder, PCB, and wire-lead options
Buyer Checks
Actuator, Sealing, and Wiring
-
Define how the actuator contacts the switch
Use a pin plunger for direct short travel, a lever for doors and lids, or a roller lever for cam-driven motion. Confirm operating position, overtravel, and lever geometry.
-
Check the required sealing boundary
Use an IP-rated series only when the product data supports the environment. If the cable exit, connector, or rear terminals can be exposed, evaluate the complete assembly rather than the switch body alone.
-
Match the electrical load
Specify voltage, current, AC or DC, load type, and switching frequency. Signal-level and power-switching duty must not be treated as interchangeable.
-
Select a production-ready termination
Choose quick-connect tabs, solder terminals, PCB terminals, or a pre-wired lead according to assembly process and service needs. Confirm connector and lead length for wired versions.
What hits the switch?
Pin, lever, or roller from the WS series
Door and lid usually take a hinge lever. Cams take a roller. Short travel in a tight housing takes a pin plunger.
Selection Guide
Match the Actuator and Load to the Switch
- Actuator and motion
- State pin, lever, or roller; include target type, travel direction, operating position, and required lever length.
- Environmental exposure
- State dust, spray, washdown, or temporary immersion exposure and whether the cable exit is exposed.
- Electrical duty
- Provide AC or DC voltage, current, load type, and switching frequency.
- Circuit function
- Specify required poles/throws and whether normally open, normally closed, or changeover contacts are needed.
- Operating force
- State the target force range and any return-force or travel requirement.
- Termination and harness
- Specify quick-connect, solder, PCB, or lead; include wire length, connector, and pinout for an assembly.

Send Motion, Load, and Sealing Requirements
Share the target motion, actuator type, voltage and current, circuit requirement, environmental exposure, and termination. DAIER can match a catalog model or review an OEM harness configuration.
Frequently Asked Questions
No. IP performance is series- and model-specific. Use the exact product drawing to confirm the required rating and assess the exposed cable exit or terminal area.
Use a pin plunger for direct compact travel, a hinge lever for doors and lids, and a roller lever for cams or sliding targets. Provide motion geometry for final selection.
Selected models are available with wire leads. Provide wire length, wire specification, connector, and pinout so the assembly can be confirmed.
Ratings vary by series from signal-level duty up to higher-current configurations. State voltage, current, AC or DC, and load type; do not select by actuator alone.
Provide a drawing or sample showing actuator type, lever length, operating position, target travel, and required electrical/termination configuration.
