Choosing the Right Anti-vandal Switch for Your Project

An anti-vandal switch is a commonly used control device that utilizes a button to activate circuit switching.

An anti-vandal switch is a commonly used control device that utilizes a button to activate circuit switching. By pressing or releasing the button, the transmission mechanism triggers the movement of contacts, either connecting or disconnecting them. This simple yet effective switch is widely employed in electrical control circuits to manually send control signals for activating contactors, relays, electromagnetic starters, and other similar devices.

Anti-vandal switches are frequently utilized in large machine tools, elevators, and other electromechanical equipment. While not as common as touch button switches, they offer enhanced durability. Thanks to their corrosion resistance, dust resistance, water resistance, as well as the use of metal keycaps and a sturdy internal structure, vandal-resistant switches have a long lifespan.

The characteristics of Anti-vandal switches

Vandal-resistant switches are designed to withstand intentional damage, tampering, and harsh environmental conditions. They are often used in applications where durability and safety are critical.

Here are some of the key features of tamper-resistant switches:

Mechanical behavior

Anti-vandal switches are renowned for their exceptional mechanical strength and durability, making them highly resistant to prolonged pressing and operation. These switches are composed of a robust metal material that enhances their compression and tensile properties, enabling them to perform admirably even in the harshest of environments. As a result, they can be relied upon for long-term and reliable operation.

High temperature resistance

Anti-vandal switches are designed to function efficiently and maintain optimal performance even in high-temperature conditions. With the ability to withstand elevated temperatures, these switches are specifically suitable for environments with demanding working conditions. The utilization of metal materials ensures durability and reliability in various settings.

Long life

The mechanical structure of the anti-vandal switch is relatively stable, and the triggering force and stroke of the button can be precisely controlled. The life of metal contacts is usually tens of thousands of times and can maintain good stable performance during long-term use.


Anti-vandal switches are equipped with specially-treated metal materials that boast exceptional corrosion resistance. These switches can withstand the erosive effects of acids, alkalis, salts, and other substances, making them perfect for deployment in a wide range of challenging environments.

Waterproof and dustproof

The anti-vandal switch has a compact structure and a certain degree of sealing, which can effectively prevent moisture, dust and other foreign matter from entering the inside of the switch, thus improving the waterproof and dustproof performance of the switch. change.

High reliability

The design structure of the anti-vandal switch is characterized by its simplicity and stability, ensuring reliable contact and a low failure rate. These switches are extensively utilized in electrical equipment and electronic products, offering a long-term and dependable operation guarantee.

How to select the correct anti-vandal switch?

Selecting the correct tamper-resistant switch requires consideration of the following factors to ensure the switch meets the specific requirements of your application.

Exterior design of Anti-vandal switch

The material selection and appearance design of anti-vandal switches are crucial in ensuring the quality, durability, and user experience of electronic devices. In addition to functional requirements, customers now place greater emphasis on the aesthetic design of switches to showcase the brand image and product aesthetics. It is essential to consider these factors when selecting and designing anti-vandal switches to create a superior user experience and strengthen the overall product appeal.

Selection of anti-vandal switch materials

When selecting anti-vandal switch materials, there are several factors to consider that may vary depending on the specific application and requirements.

Metal: Metal is a popular choice for vandal-resistant switches due to its durability and resistance to impact and vandalism. Commonly used metal materials include stainless steel, brass and aluminum. Stainless steel is preferred for its corrosion resistance and sturdiness, making it suitable for use in harsh environments. Brass is more aesthetically pleasing and is often used in high-end applications. Aluminum is lightweight and can be anodized or painted for extra protection. Plastic: While plastic may not be as durable as metal, it can still provide adequate protection from vandalism in less demanding environments. Polyamide (nylon) and polycarbonate are commonly used plastic materials for tamper-resistant switches. These materials can be reinforced to increase their strength and impact resistance. Sealing: Depending on application requirements, it may be necessary to select switch materials with sealing properties. This is critical for switches exposed to dust, moisture, or other elements. Sealing capabilities can be enhanced by selecting materials with a higher IP (Ingress Protection) rating.

Design and appearance of anti-vandal switches

Vandal-resistant switches are designed to be rugged, secure, and resistant to tampering or intentional damage. They are often used in applications that require robust and reliable control, such as public spaces, industrial settings or outdoor environments. The design and appearance of vandal-resistant switches often reflect their ruggedness and protection.

Shape and size:
The shape design can be customized according to product requirements, such as square, round, oval, etc., to meet different operating habits and space constraints.
The size design should consider ergonomic principles and practical application needs to ensure that the buttons are easy to operate and comply with the size and strength of the human hand.
Color and surface treatment:
The choice of color should match the overall style and brand image of the product, which can be achieved through surface treatment technologies such as spraying and electroplating.
Surface treatment technologies such as anodizing, sandblasting, and polishing can not only improve the appearance and texture of the switch, but also enhance its corrosion resistance and wear resistance.

How To Wire the Anti-Vandal Switch?

In English, we will now introduce the characteristics and usage scenarios of two wiring methods commonly used for anti-vandal switches: single-pole and bipolar. Single-pole wiring involves connecting the switch to one circuit, while double-pole wiring connects the switch to two circuits. These wiring methods have specific applications and functionalities which we will outline for you.

Unipolar wiring

The most widely used wiring method for tamper-resistant switches is single-pole wiring. With this method, the switch is connected to a single circuit. Single-pole wiring is commonly employed to control the switching of individual devices or circuits, such as lighting, fans, and motors.

Wiring method:

Unipolar wiring connects one end of the tamper-resistant switch to ground and the other end to the circuit’s positive or negative pole. In a single-pole wired vandal switch, one pin is connected to the switch’s metal housing as ground, while the other pin serves as the circuit’s input or output. Pressing the switch connects or disconnects the circuit, allowing for on-off control.

Bipolar wiring

Bipolar wiring is another common wiring method for vandal-resistant switches. This type of wiring, in which the switch is connected to two circuits at the same time, is often used to control switches for multiple devices or circuits. For example, bipolar wiring can be used to control the switching of equipment such as fans and lighting.

Wiring method:

Bipolar wiring connects two pins of a switch to create a complete circuit. A metal key switch usually has four pins, two of which are connected to the metal shell as ground. The other two pins are connected to the positive and negative terminals as input or output. Pressing the switch connects or disconnects the circuit to control its on-off state.
