Collection: Limit & Micro Switches

Limit And Micro Switches For Industrial Controls And Machinery

We offer a selection of long lasting Limit and Micro Switches with a typical mechanical life of at least 10 million cycles. They can be used as an economical alternative for many 'Big Brand' Limit and Micro switches without compromise. 

What Is The Difference Between A Limit And Micro Switch?

We normally consider a Limit Switch to be an industrial product in a housing. They are larger than a microswitch and can be found on machines and production lines where greater forces are anticipated. Microswitches by comparison are smaller and may have more subcomponents exposed such as the electrical terminals and some parts of the operating mechanism. Microswitches are normally housed inside another part or enclosure whereas limit switches can usually be mounted as a standalone component.

Where Are Limit Switches Used In Industry? 

Limit switches are commonly used to detect presence of objects and end of movement. Our EMAS Limit Switches are an industrial product suitable for repeated operation in factory automation and OEM machinery. We offer the metal body type which gives a greater level of mechanical protection. Our limit switches accept standard electrical glands, with all of the internal wiring protected from dust and liquid ingress. 

How To Choose A Microswitch

When choosing a microswitch it is important to consider the actuator type. This is the mechanism that operates the electrical contacts. Common actuators include lever, plunger, roller and button. It is important to consider the range of motion and force required to operate the switch. 

Another important factor is the voltage and current ratings. Many low priced microswitches are not rated to 240V AC and only switch small currents. Our EMAS products are rated to 250V and 10A AC1.

EMAS microswitches are available in many different formats. For greater versatility we offer the changeover contact as standard which allows the switch to be wired for normally closed or normally open. Micro switches are compact, allowing installation in enclosed spaces. As such they can be found in the smallest of handheld devices. For example, as part of the trigger mechanism.
