APEM Toggle Switch, PCB Mount, (On)-Off-(On), SPST, Through Hole Terminal, 20V ac/dc


Toggle switches are manual control components used across a wide range of industries for switching devices or electrical circuits ON and OFF. These mechanical electrical switches have a lever or handle that can be flipped up or down to control the flow of electricity. 

Toggle switches operate by moving internal metal contacts through a mechanical lever mechanism inside the switch. Flipping the lever in one direction connects the contacts and completes the circuit (“ON” position), while flipping it the other way separates the contacts, breaking the circuit (“OFF” position). Their mechanical design offers tactile feedback and a clear visual indication of switch status, making them simple and intuitive to use.

Toggle switches are compatible with both low- and high-voltage circuits, from basic household appliances to complex industrial machinery.

You’ll find a wide selection of toggle switches at RS, including waterproof, panel-mount, heavy-duty, and miniature types, all available at competitive prices in the Philippines.

## **What Are Toggle Switches and How Do They Work?**

Toggle switches are manually actuated devices featuring a lever or handle that flips internal metal contacts to open or close electrical circuits. Most employ a positive snap-action mechanism that ensures a definite “click” when switched, enhancing reliability and user confidence.

There are two main types: basic ON/OFF configurations like SPST, which connect or disconnect a single circuit, and SPDT, which alternate one input between two outputs, ideal for selecting between circuits. Additionally, momentary toggle switches, such as (ON)-OFF-(ON) variants, feature springs that automatically return the lever to a default position, facilitating temporary activation, ideal for controls like reset buttons or horns.

Toggle switches are valued for their durability, straightforward operation, and tactile feedback make them suitable for industrial control panels, residential lighting, and automotive applications, delivering precise, dependable operation with each flip of the lever.

## **Types of Toggle Switches Available**

Toggle switches come in a wide range of designs tailored to specific mounting needs, environments, and electrical configurations. Here's a breakdown of the most common types:

### **Panel Mount Toggle Switches**

A panel mount toggle switch is commonly used in dashboards, control panels, and equipment boxes. These switches are easy to install, provide quick access for operators, and offer a secure fit with threaded bushings for mounting.

### **Waterproof Toggle Switches**

Designed for harsh or outdoor settings, waterproof toggle switches include sealed housings and gaskets to prevent moisture, dust, or debris from entering. Ideal for marine, automotive, and construction equipment, these are reliable even in extreme environments.

### **Heavy-Duty Toggle Switches**

A heavy-duty toggle switch is built to handle high-current applications and rugged industrial use. These often include reinforced metal levers, robust casings, and higher voltage ratings, making them perfect for heavy machinery or commercial systems.

### **Latching Toggle Switches**

These switches stay in the ON or OFF position until manually changed. Perfect for maintaining a circuit state, latching toggle switches are widely used in lighting and power control.

### **Momentary Toggle Switches**

A momentary toggle switch activates a circuit only while being pressed or held, returning to its original position when released. They are commonly used in signaling devices, reset controls, and applications requiring temporary voltage application.

### **SPST / SPDT / DPDT Configurations**
- SPST toggle switches control a single circuit with a basic ON/OFF function.
- SPDT toggle switches route current between two outputs, suitable for 2 way toggle switch setups.
- DPDT (Double Pole Double Throw) switches control two circuits simultaneously and are useful in reversing motor directions or complex controls.

## **Benefits of Using Toggle Switches**

Toggle switches are widely trusted for their simplicity and efficiency, offering a reliable control solution for everyday and industrial applications. Here are some key benefits:

- **Simplicity and Tactile Feedback:** Electrical toggle switches have a straightforward mechanism and provide tactile feedback, making them easy to operate and ideal for quick manual control.
- **Visual ON/OFF Position Indication:** These toggle switches offer a clear visual indicator, usually an up or down lever position, so users can easily confirm if the switch is ON or OFF.
- **Durability in Tough Conditions:** Many industrial toggle switches are built with rugged materials and are resistant to dust, moisture, and vibrations, ensuring long-lasting performance in demanding environments.
- **Cost-Effective Control:** Toggle switches are affordable, making them a cost-effective choice for DIY projects or as reliable control components in industrial systems.
- **Versatility in Size and Capacity:** Available in compact versions for small devices or heavy-duty for high-current systems, toggle switches suit a wide range of applications across voltage levels.

## **Where Are Toggle Switches Used Across Industries?**

Toggle switches are reliably used across diverse industries for manual control, signaling, and circuit selection due to their durability, simplicity, and flexible configurations. Here’s how different sectors in the Philippines leverage them:

- **Discrete Manufacturing:** In automobile assembly plants and machinery control lines, robust industrial toggle switches (SPST or SPDT) are used to control machinery, lights, or conveyor functions. Their rugged build helps cope with frequent use and harsh production environments.
- **Process Manufacturing:** Hygienic or sealed styles are used in food and pharmaceutical processing to activate mixers, pumps, or valves manually. Waterproof or dust-proof toggle switches help maintain cleanliness and contamination-free operations.
- **Energy and Utilities:** Control panels in power substations and plant backup systems often feature high-current toggle switches, including DPDT configurations. Their reliability supports load switching and emergency controls in critical installations.
- **Facilities and Intralogistics:** Common for lighting circuits, mobile testing benches, and carts, SPST panel toggles are used for ON/OFF control in low-voltage systems. Vandal-resistant or locked toggle designs are sometimes used for public-area safety switches.

## **How to Choose the Right Toggle Switch**

Choosing the right toggle switch ensures reliable performance and safety. Consider these key criteria:

- **Circuit Configuration:** Select between SPST, SPDT, or DPDT switches depending on how many circuits you need to control and toggle between. SPST offers simple ON/OFF control, SPDT allows switching between two outputs, and DPDT supports two circuits simultaneously.
- **Current Rating:** Check the switch’s amperage and voltage ratings to match your application. For high-current uses, opt for a toggle switch with reinforced contacts and greater capacity.
- **Mounting Style:** Determine whether you need a panel mount toggle switch, PCB mount, or surface mount. Panel-mount types have threaded bushings, while PCB styles are compact for circuit boards.
- **Environmental Needs:** If the switch is exposed to moisture, dust, or vibration, choose a waterproof toggle switch with a suitable IP rating. These are essential for outdoor, marine, or industrial environments.
- **Switch Action:** Decide between latching (maintains position) for sustained ON/OFF control, or momentary (returns to original position) for temporary signals like in reset or horn circuits.
