Types of Door Release Switch

Door release switches are installed in various settings to provide convenience and safety. An automatic door release switch is installed in automatic doors. When pressed, the switch sends a signal to the door control system to open the door. These switches are used in buildings with high traffic, emergency exits, and where door access for disabled people is required.

The second type of door release switch is the electric strike release switch. It is connected to an electric strike lock. When a signal is sent by the switch, the lock disengages, allowing entry. Access control systems and door intercoms commonly use this type of door release switch.

Another type of door release switch is a remote release switch. This switch can be used to open a door from a distance. They are useful in settings where physical presence is not possible, such as parking garages, loading docks, and some medical facilities.

Wireless door release switches are becoming common because of technological advancements. These door release switches are based on wireless technology, such as Wi-Fi or Bluetooth. They eliminate the need for complicated wiring setups. They are suitable for retrofitting access control systems into existing buildings.

Push button door release switches are the most common type. They have simple and easy-to-use interfaces. Users are required to push a button to release the lock and gain access. They come in various designs, such as momentary and latching.

Momentary push button switches have temporary contact. The circuit is completed as long as the button is pressed and broken once released. They are ideal in situations where temporary access is required.

Latching push button switches have a maintained contact. The circuit is closed until the button is pressed again. They are suitable for applications where continuous access is required.

Key switch door release switches require a key to operate. This adds an extra layer of security, making them suitable for sensitive areas where access control is crucial. They are used in data centers, server rooms, and places where valuable assets are stored.

Toggle switch door release switches are traditional door release switches. They have on and off positions that make them easy to use. They are reliable and suitable for simple access control applications.

Security door release switches are designed to minimize unauthorized access to restricted areas. They are combined with other security systems, such as alarms or surveillance cameras, to enhance security. They are suitable for banks, jewelry shops, and areas with high security needs.

Emergency door release switches are designed to be used in emergencies. They have distinctive colors and markings to be easily identifiable. They are installed in places where quick door access is essential, such as emergency exits, hospitals, schools, and public buildings.

Specification and Maintenance of Door Release Switch

Specifications of door release switches vary depending on their design, the number of contacts, and the voltage ratings. Here are some common specifications

• Voltage and Current Rating

  Voltage and current ratings on door release switches are important for safety and functionality. The rating should be equal to the intended use. For instance, when the switch is used with low voltage systems, like intercom or access control systems, it should have a voltage rating of 12V to 24V DC.

• Contact Configuration

  Door release switches have different contact configurations. This feature determines their operation mode. Common configurations are normally open (NO) and normally closed (NC) contacts. NO contacts are momentary and only close when pressed. They are used for non-latching operations. On the other hand, NC contacts are latching and remain closed until pressed.

• Material

  The materials used to make door release switches affect their longevity and functionality. The housing is often made of durable materials such as plastic or metal. On the other hand, the switch mechanism is usually made of corrosion-resistant materials like stainless steel.

• Size and Mounting

  Door release switches come in different sizes. The size depends on the application and the available installation space. Also, the mounting options vary depending on the design of the switch. Some door release switches are surface-mounted, while others are recessed-mounted.

Regular maintenance of door release switches is crucial for safety and functionality. Here are some maintenance tips

• Inspect

  Regularly inspect door release switches for signs of wear and tear. Look out for loose connections, damaged buttons, or corrosion.

• Clean

  Clean the switches at regular intervals to avoid the accumulation of dust and debris. Use a soft cloth and a mild cleaner. Also, clean the surrounding areas to enhance the visibility and functionality of the switches.

• Lubricate

  Door release switches have moving parts that require periodic lubrication. Use a suitable lubricant to minimize friction and ensure smooth operation.

• Test

  Regularly conduct functionality tests to ensure the door release switch is operating as required. Perform voltage and current tests to confirm they are within the specified ratings.

• Replace

  Replace worn-out or damaged components immediately. Use original replacement parts to ensure compatibility and reliability.

How to Choose Door Release Switch

Choosing an electric door release switch requires careful consideration of various factors to ensure compatibility, functionality, and security requirements are met. Here are some key factors to bear in mind:

• Compatibility:

  The compatibility of the door release switch with the existing access control system is essential. Find out whether the system is integrated with intercom systems, keypads, or card readers. Also, consider the compatibility of the door release switch with the door type, door hardware, and wiring configuration.

• Security Level:

  Consider the security level required for the door in question. For high-security areas, more secure electric door release switches like electromagnetic locks or electric strike locks may be necessary. For average security areas, standard door release switches may be sufficient.

• Functionality:

  Determine the required functionality of the door release switch. Should it be a momentary switch (push to release) or a latching switch (push once to release)? Consider whether additional features like timers, indicators, or integration with alarm systems are needed.

• Power Supply:

  Consider the power supply requirements of the door release switch. Ensure that the power supply is available and compatible (voltage and current) with the chosen switch. Consider backup power options like UPS (Uninterruptible Power Supply) for critical security systems.

• Installation:

  Consider the installation requirements of the door release switch. Determine whether it can be installed easily or if any additional modifications or preparations to the door or the surrounding area are needed. Also, consider the mounting options, wiring requirements, and overall installation process.

• Durability and Reliability:

  Consider the durability and reliability of the door release switch. Select options that are resistant to wear, weather conditions, and tampering. For critical security applications, redundant or fail-safe features may be necessary to ensure reliability.

• Compliance:

  Find out whether the door release switch complies with relevant industry standards and local regulations. This may include electrical safety standards, accessibility requirements (e.g., ADA compliance), and building code regulations.

• Budget:

  Consider the budget for the door release switch and the overall access control system. Get quotes from different suppliers, evaluate the features and benefits of each option, and choose the one that meets the requirements within the budget.

It is advisable to consult with a professional who specializes in access control systems and security solutions to select the most appropriate door release switch for a specific application. They can assess the requirements, recommend suitable options, and ensure proper installation and configuration for maximum security and convenience.

How to DIY and Replace Door Release Switch

Replacing a door release switch can be a simple DIY task. With the right tools and basic knowledge of car electronics, it can be done. The tools needed for this task are a screwdriver set, wire strippers, electrical tape, safety glasses, and a new door release switch. The new door release switch should be compatible with the vehicle to ensure it functions properly.
