Magnetic Catches vs Push-to-Open Latches: Lockless Furniture Closing Systems

A magnetic catch passively secures a closed furniture door using magnetic force, whereas a push-to-open latch actively pushes the door open via an integrated spring following a light press on the front.

Handleless fronts are the technical standard in contemporary furniture making. Anyone designing a modern, flush-fitted wall unit dispenses with classic handles. To ensure doors remain easy to operate and stay securely closed, concealed closing systems are used. These systems take over the role of handles and often replace simple furniture locks when physical locking is not required, but holding the door in place is essential. Choosing between a magnetic catch and a mechanical push system significantly defines the cabinet carcass construction, the gap reveal, and the choice of hinges.

What is a Magnetic Catch?

A magnetic catch is a passive fitting consisting of a plastic or metal housing with an integrated magnet, alongside a metallic counterpart. This counterpart, the counterplate, is screwed to the inside of the furniture door.

When the door closes, the magnet attracts the plate and keeps the front flush against the carcass. The holding force is specified in kilograms and typically ranges between 2 kg and 4 kg for standard furniture. To open the door, the magnetic force must be overcome by pulling manually on the front edge. Magnetic catches require no inward trigger travel. When closed, the door can rest directly against the front edge of the carcass or on a buffer pad.

What is a Push-to-Open Latch?

A push-to-open latch—often referred to in the industry as push-to-open or tip-on—is an active ejection system. The cylindrical component contains a tensioned spring and a movable pin, the plunger. The internal mechanism functions exactly like a ballpoint pen: one push engages the mechanism, another push releases the catch.

When the user presses lightly against the furniture door from the outside, the plunger is depressed inwards by approx. 2 mm - 3 mm. This unlocks the mechanism. The spring extends and pushes the door open by 20 mm - 40 mm. The resulting gap is sufficient to reach behind the front with fingers and pull the door open completely. This principle applies not only to revolving doors, but also in modified forms to push to open drawer runners.

Detailed Technical Differences

The choice between these two systems impacts the entire hardware specification of the furniture piece. The following parameters differ fundamentally:

• Trigger travel: A push-to-open latch forces the designer to maintain a defined gap reveal. For the door to press the plunger inwards, a gap of at least 2 mm - 3 mm must remain between the door and carcass. A magnetic catch does not require this gap; the door closes completely flush.
• The closing action: A door with a magnetic catch is simply pushed shut or closes by itself through the momentum of the hinge. With a push-to-open mechanism, the door must be actively pushed against the plunger until the mechanism audibly clicks into place.
• Hinge compatibility: This is the most critical factor during installation. A magnetic catch requires classic concealed cup hinges / cabinet hinges with an integrated closing spring (catch mechanism). The spring pulls the door over the final centimetres, and the magnet handles the rest. A push-to-open latch strictly requires hinges without a catch mechanism (free-swinging hinges) or special unsprung / reverse-spring hinges. Using a push-to-open latch with a standard sprung hinge causes the hinge spring and the latch spring to work against each other.

Which System is Best Suited for Which Application?

Choosing the right system depends on the weight of the front, the desired aesthetic, and the type of furniture unit.

Applications for Magnetic Catches

Magnetic catches are the technically simpler solution. They are exceptionally well suited to lightweight doors made from MDF or chipboard, as well as for retrofitting existing cabinets. If a door no longer closes flush due to material warping, the magnet reliably pulls it tight against the carcass. Magnetic catches (combined with a clip-on glass counterplate) are also the standard choice for glass fronts in display cabinets where a showcase lock would disrupt the aesthetic.

Applications for Push-to-Open Latches

When planning modern wall units, push-to-open latches are the preferred choice. The flush, handleless appearance of modern wooden or high-gloss units can only be realised in this manner. Because fronts are often heavy, the ejection spring force must be precisely matched to the door weight. Many manufacturers offer the plunger with an integrated magnetic tip. This additionally secures the door to the carcass when closed and prevents it from popping open in light draughts.

Installation and Adjustment

Installing both systems requires precision, yet the execution differs.

Magnetic catch installation: The housing is fastened inside to the carcass side panel or top panel using chipboard screws. Precise alignment of the counterplate on the door is vital. To locate the position, place a small piece of double-sided adhesive tape on the counterplate, attach it to the magnet, and press the door firmly shut. The plate will adhere to the exact drilling position on the door.

Push-to-open installation: Two variants exist. The flush-fit version requires a hole drilled directly into the front edge of the carcass side (typically 10 mm in diameter and 50 mm deep). The cylinder is simply inserted into the borehole. Alternatively, the latch clips into an adapter plate, which is screwed to the inside of the carcass as a cross mounting plate. After installation, the trigger travel must be adjusted. By rotating the plunger, its length can usually be adjusted by +3 mm / -1 mm to fine-tune the door gap reveal perfectly.

FAQ – Frequently Asked Questions About Closing Hardware

Can I combine push-to-open latches with soft-close hinges? No, this is physically contradictory. Concealed cup hinges / cabinet hinges with soft-close damping brake the door when closing and pull it shut gently. A push-to-open latch, however, requires closing momentum to engage the internal spring. Damping neutralises this momentum, leaving the door standing slightly ajar.

Which hinge do I need for a push-to-open latch? For smooth operation, you need unsprung hinges without an automatic closing spring. A typical 110-degree concealed cup hinge without a spring mechanism ensures the door encounters no resistance when swinging open after the plunger triggers.

Why does my push-to-open door not open far enough? This usually has two causes: either the door weight is too heavy for the installed ejection spring, or sprung hinges were fitted by mistake. The hinge spring pulls against the plunger and restricts the throw distance.

How wide must the gap be for a push-to-open latch? The trigger gap is strictly required and ranges between 2 mm - 3 mm depending on the model. If the door sits tightly against the carcass without a gap, the plunger cannot be depressed inwards, and the mechanism will not release.
