WLCA12N WLCA12N is a metal travel switch designed for reliable, waterproof end switch operation in DC circuits. It is rated for 1 A at 125 V DC, making it suitable for on/off control in environments where moisture resistance is important. WLCA122N The WLCA122N variant provides a defined contact state with 1 open and 1 closed. This gives a clear on/off behavior in your DC circuits when the switch is actuated. WLCA122NN The WLCA122NN designation is the same as WLCA122N, offering the same electrical characteristics and state configuration. Key benefits - Waterproof performance: built to resist moisture exposure, supporting reliable switching in wet or damp environments. - Durable construction: metal housing provides robust protection for travel switch applications. - Clear on/off control: the 1 open/1 closed state in WLCA122N variants delivers straightforward, predictable switching behavior. - DC compatibility: rated 1 A at 125 V DC, suitable for controlling DC circuits and devices within this rating. What this enables - Reliable control of low-current DC loads in exposed or washdown areas without risking moisture-related failures. - End-switch style switching that integrates with actuator or travel-based triggering in compact, durable form factors. - Interchangeable understanding: WLCA122NN is functionally the same as WLCA122N, offering flexibility in component labeling or sourcing. Use scenarios - Outdoor or maritime equipment: use to switch a DC pump or relay in weather-exposed locations such as weatherproof enclosures, decks, or wet areas. - Industrial automation in damp environments: control a DC motor or valve in areas prone to moisture or washdown where a robust end-switch is required. - Off-grid or exposed installations: implement reliable on/off control for small DC circuits in garden, farm, or remote equipment where waterproof switching is essential. Notes - Model variants provided here reflect the same core function and electrical ratings, with WLCA122N offering 1 open and 1 closed states, and WLCA122NN representing the same specification as WLCA122N. - Ensure the use stays within the 1 A at 125 V DC rating for safe, reliable operation.
