A thumb latch is a type of door handle that allows you to open and close a door with just the push of a thumb. The latch consists of two parts: a latch that is mounted on the door and a lever that is attached to the door frame. When the lever is pushed, the latch is released, allowing the door to open.
Thumb latches are used on a variety of doors, including interior and exterior doors, sliding doors, and even gates. They are especially popular on doors that are used frequently or are in public areas, as they are easy to use and require minimal effort to open.
The most common type of thumb latch is the deadbolt latch. This type of latch consists of a plate that is mounted on the door and a lever that is attached to the door frame. The plate has a hole in it that is connected to the lever. When the lever is pushed, it pushes the plate, which in turn releases the latch and allows the door to open.
The second type of thumb latch is the spring-loaded latch. This type of latch is similar to the deadbolt latch, but instead of a plate, it has a spring-loaded arm that is connected to the lever. When the lever is pushed, the arm is released, allowing the latch to open.
The third type of thumb latch is the mortise latch. This type of latch has a plate that is connected to the door and a lever that is attached to the door frame. The plate has a slot that is connected to the lever. When the lever is pushed, it pushes the plate, which in turn releases the latch and allows the door to open.
The fourth type of thumb latch is the cam latch. This type of latch has a plate that is connected to the door and a lever that is attached to the door frame. The plate has a slot that is connected to the lever. When the lever is pushed, it moves the plate, which in turn releases the latch and allows the door to open.
The fifth type of thumb latch is the roller latch. This type of latch has a plate that is connected to the door and a lever that is attached to the door frame. The plate has a slot that is connected to the lever. When the lever is pushed, it moves the plate, which in turn releases the latch and allows the door to open.
No matter which type of thumb latch you choose, they all work in the same basic way. When the lever is pushed, the plate or arm is released, allowing the latch to open and the door to be opened. Thumb latches are easy to use and require minimal effort to open, making them a popular choice for doors that are used frequently or are in public areas.
