Omron V-155-1A5 Basic Switch 15A

Mechanical Limit and Interlock Detection with Snap-Action Reliability

V-155-1A5 is part of Omron V-series basic switch family, a widely used category of snap-action devices in industrial and electromechanical applications. This switch class is commonly chosen for door interlocks, actuator end-position detection, mechanism presence checks, and auxiliary status signaling. Snap-action construction provides clear state change behavior for control logic and safety-adjacent interlock schemes where deterministic contact transition is important. During design, integrators should confirm actuator force profile, mounting tolerance, mechanical overtravel limits, and electrical load category to ensure long service life. In machine service environments, V-series style switches remain popular because they are familiar to maintenance teams and straightforward to replace. V-155-1A5 is typically used when practical reliability, simple integration, and repeatable mechanical switching are key project priorities.
