Product Overview
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.

Buying Checklist
- Verify actuator type and operating force against mechanism dynamics.
- Check contact rating and load category for driven circuit safety margin.
- Confirm environmental protection requirements at installation location.
- Review mounting tolerance and allowable overtravel for long switch life.
- Plan preventive inspection interval based on cycle count and duty severity.

FAQ for V-155-1A5
What applications use V series basic switches?
General purpose switching: appliances, industrial equipment, control panels, HVAC systems. 15A rating suits moderate power loads.
What's the difference between V and Z series?
V series: general purpose, cost-effective. Z series: industrial grade, higher mechanical life, more actuator options. Choose Z for demanding industrial applications.
Can I use this switch for motor control?
For small motors under 15A, yes. For larger motors, use switch to control contactor coil. Motor loads are inductive - consider contact rating for inductive loads.
What's the maximum switching frequency?
For resistive loads: up to 1800 operations/hour. For inductive loads: reduce to 600 operations/hour. For higher frequency, consider solid state switching.
