22mm LA38 Push Button Switch, YiJia Waterproof Momentary/Latching Power Switch, 1NO1NC/2NO Silver Contact, 10A, for Industrial Control & DIY Projects

Product Description


This is the YiJia LA38 (YJ139-LA38) series waterproof push button switch, a reliable solution for industrial control, power start/stop, and DIY electrical projects. Designed with a 22mm mounting hole, it supports two operation modes:

  • Momentary (Self-reset): Automatically rebounds when released, ideal for temporary control signals.
  • Latching (Self-locking): Stays engaged until pressed again, suitable for continuous power control.

Key features:

✅ Flexible Contact Options: Choose between 1NO1NC (1 Normally Open + 1 Normally Closed) or 2NO (2 Normally Open) configurations to match your circuit needs.

✅ Silver Alloy Contacts: Durable silver alloy contacts ensure stable conductivity and long service life, rated up to 10A for low-power circuits.

✅ Waterproof & Dustproof: IP-rated design protects against splashes and dust, suitable for humid or industrial environments.

✅ Multi-Color Selection: Available in green, red, yellow, black, and white to meet different functional and visual requirements (e.g., green for start, red for stop).

✅ Universal Compatibility: Works with AC/DC circuits below 380V/230V, widely used in control panels, machinery, home appliances, and automation systems.
