3. Housing & Environmental Durability
Premium Material Construction
- Outer shell: SUS304 stainless steel, optional brass nickel-plated or anodized aluminum alloy
- Button cap: PC plastic + SUS316 stainless steel composite
- Base body: Modified nylon PA66 high-temperature resistant engineering plastic
- Sealing grade: IP67 waterproof at button end, dust-proof, splash-proof, resistant to light water immersion
Wide Working Temperature Range
Operates stably from -30°C to +85°C, suitable for cold outdoor sites, high-temperature workshop machinery and refrigeration equipment control systems.
4. Working Mode & Wiring Diagram
Two core functional modes optional during ordering:
- Self-resetting (momentary): Circuit closes when pressed, cuts off once released – standard for jog control, signal trigger
- Self-locking (latching): Press once to lock ON, second press to unlock OFF – perfect for long-time power keep circuits
Standard wiring logic:
- Single-color lamp: Non-polar positive-negative connection
- Dual-color lamp: Reversible pole wiring to switch between two light hues for different equipment states
Circuit schematic clearly marks NO (Normally Open) terminal for simple field wiring without professional electrician support.
