Micro Switch Roller Lever Snap Action 10A V1518705 Auspicious

The Auspicious V1518705 is a roller lever micro switch from the V15-187 series, supplied as a pack of two. The roller sits at the end of a sprung lever, so a cam or moving part presses the lever down rather than pushing directly onto a plunger. That gives a longer operating travel and a lighter actuating force than a plain plunger type.

Snap action is what makes a micro switch different from an ordinary switch. The internal mechanism holds until a set point, then flips the contacts across in one fast movement regardless of how slowly the lever is being pressed. The contacts never sit half open arcing, which is why this type lasts for a million mechanical operations and a hundred thousand at full electrical load.

It is rated 10A at 250V AC with one normally open and one normally closed contact sharing a common pin, so three terminals cover both functions. The body is built for mounting inside appliances and equipment rather than onto a machine frame, accepting 1.0 to 2.5mm conductors. A 2500V impulse withstand rating and level 3 glow wire test result mean it meets the safety requirements for built in appliance use. TUV and CE certified, made in Taiwan.

Technical Specifications

Common Applications

Appliance door and lid interlocks, vending and dispensing mechanisms, printers and office equipment, coin and card readers, small automation jigs, test and measurement rigs, safety interlocks inside enclosures, and OEM equipment where the switch is built into the product rather than mounted on a frame.

Choosing the Right Switch

A V series micro switch is designed to be built into equipment. It has no sealed housing, so it is not the right choice for a machine frame exposed to dust, coolant or weather. For those positions you need a sealed limit switch with its own enclosure.

In that case, the adjustable roller lever mini limit switch AZ-8108 gives the same roller lever action in an IP65 metal body, and the adjustable rod limit switch AZ-8107 uses a flexible rod for long reach. For heavier duty, the adjustable roller lever limit switch AZ-5108 carries 10A in a larger body and the big wheel limit switch AZ-5108L is IP67 rated for lifts and cranes. Where a cam presses straight down, the roller plunger limit switch AM-1308 handles 15A, and the cross roller plunger limit switch ME-8122 accepts approach from more than one angle.

FAQ,s

What is a roller lever micro switch?

It is a small snap action switch with a roller mounted on a sprung lever. Pressing the lever operates the contacts, and the roller lets a cam slide past without wearing the lever down.

What does snap action mean?

The contacts hold position until a set trip point, then transfer across in one quick movement no matter how slowly the lever is pressed. That avoids slow arcing and gives the switch its long service life.

What is the difference between a micro switch and a limit switch?

A micro switch is the bare switching element, built into equipment. A limit switch is usually the same mechanism housed in a sealed enclosure for mounting on a machine frame or outdoors.

How many contacts does it have?

One normally open and one normally closed, sharing a common pin. Three terminals in total.

How long does it last?

At least one million mechanical operations and 100,000 electrical operations at full load.

Is this sold individually?

No, it is supplied as a pack of two.
