‘Push to Exit’ buttons are an important part of access control applications. Mount the spring-loaded button – which comes in different styles – on a stainless steel plate.

In this post, we’ll present four suggestions for choosing the right push button switch for your access control system. Note that there are two methods for passing in and exiting out of access control systems –

First Method:

Read the card when either entering or exiting the building. We refer to the card as a ‘two-way read card’ or a ‘two-way entrance card’. The advantage of reading the card when entering or exiting is that it provides a high level of security. The card typically doesn’t leave the building, so there’s always a record showing who exited the door, and when.

Second Method:

Read the card when entering and press the push button to ensure the door unlocks when exiting the building. We refer to this as the ‘one-way entrance guide’ or the ‘one-way read card’. This is possibly a more convenient and less costly approach; however, the security level is lower. For cost-effectiveness reasons, this method is more popular than the first method and is mostly used in office access departments.

The Push Button

The ‘push button’ (also referred to as a ‘door button’) is an important part of the access control device.

The idea behind a push button is the same as that of a doorbell button. When you press the button, the two internal contacts guide the button. When you release the button, the button bounces back and disconnects the contact.

Some projects have a doorbell button on the door button, with the doorbell button having a ‘bell’ pattern on it.

Different Types of Push Buttons

Material: There are plastic buttons and metal buttons. While the metal button looks more expensive and feels harder, it has a shorter lifespan than the plastic button. The plastic button looks cheaper, but it’s durable and will outlast a metal button.

Size: Divide the size into ‘small button’ and ‘86 boxes button’. The small button comes in many sizes, and while it’s beautiful to look at, the quality is lower than the 86 boxes button. Generally, use the 86 boxes button in applications like the bottom box of a fluorescent lamp switch and on wall outlets.

Here Are Our 4 Suggestions for Model Selection

No. 1: If your building is a standardized construction and utilizes a weak current system, our first recommendation is to use an 86-bottom box button.

No. 2: We recommend using the metal button in high-grade situations where appearance is important.

No. 3: Use the plastic button if you’re looking for simplicity, low cost, and an attractive appearance.

No. 4: Where it’s difficult to use an 86 bottom box due to the size of the installation space, as in a stainless steel door frame, we suggest using the small button.
